4. God were not eternal if he were mutable. In all change there is something that perishes, either substantially or accidentally. All change is a kind of death, or imitation of death; that which was dies, and begins to be what it was not. The soul of man, though it ceaseth not to be and exist, yet when it ceaseth to be in quality what it was, is said to die. Adam died when he changed from integrity to corruption, though both his soul and body were in being (Gen. ii. 17); and the soul of a regenerate man is said to “die to sin,” when it is changed from sin to grace (Rom. vi. 11). In all change there is a resemblance of death; so the notion of mutability is against the eternity of God. If anything be acquired by a change, then that which is acquired was not from eternity, and so he was not wholly eternal; if anything be lost which was from eternity, he is not wholly everlasting; if he did decrease by the change, something in him which had no beginning would have an end; if he did increase by that change, something in him would have a beginning that might have no end. What is changed doth not remain, and what doth not remain is not eternal.614 Though God alway remains in regard of existence, he would be immortal, and live alway; yet if he should suffer any change, he could not properly be eternal, because he would not alway be the same, and would not in every part be eternal; for all change is finished in time, one moment preceding, another moment following; but that which is before time cannot be changed by time. God cannot be eternally what he was; that is, he cannot have a true eternity, if he had a new knowledge, a new purpose, a new essence; if he were sometimes this and sometimes that, sometimes know this and sometimes know that, sometimes purpose this and afterwards hath a new purpose; he would be partly temporary and partly eternal, not truly and universally eternal. He that hath anything of newness, hath not properly and truly an entire eternity. Again, by the same reason that God could in the least cease to be what he was, he might also cease wholly to be; and no reason can be rendered why God might not cease wholly to be, as well as cease to be entirely and uniformly what he was. All changeableness implies a corruptibility.

5. If God were changeable, he were not infinite and almighty. All change ends in addition or diminution; if anything be added, he was not infinite before, if anything be diminished, he is not infinite after. All change implies bounds and limits to that which is changed; but God is infinite; “His greatness is unsearchable:”615 we can add number to number without any end, and can conceive an infinite number; yet the greatness of God is beyond all our conceptions. But if there could be any change in his greatness for the better, it would not be unsearchable before that change; if for the worse, it would not be unsearchable after that change. Whatsoever hath limits and is changeable, is conceivable and searchable; but God is not only not known, but impossible in his own nature to be known and searched out, and, therefore, impossible to have any diminution in his nature. All that which is changed arrives to something which it was not before, or ceaseth in part to be what it was before. He would not also be almighty. What is omnipotent cannot be made worse; for to be made worse, is in part to be corrupted. If he be made better, he was not almighty before; something of power was wanting to him. If there should be any change, it must proceed from himself or from another; if from himself, it would be an inability to preserve himself in the perfection of his nature; if from another, he would be inferior in strength, knowledge, and power, to that which changes him, either in his nature, knowledge, or will; in both an inability; an inability in him to continue the same, or an inability in him to resist the power of another.

6. The world could not be ordered and governed but by some Principle or Being which were immutable. Principles are alway more fixed and stable than things which proceed from those principles; and this is true both in morals and naturals. Principles in conscience, whereby men are governed, remain firmly engraven in their minds. The root lies firmly in the earth, while branches are shaken with the wind. The heavens, the cause of generation, are more firm and stable than those things which are wrought by their influence. All things in the world are moved by some power and virtue which is stable; and unless it were so, no order would be observed in motion, no motion could be regularly continued. He could not be a full satisfaction to the infinite desire of the souls of his people. Nothing can truly satisfy the soul of man but rest; and nothing can give it rest but that which is perfect and immutably perfect; for else it would be subject to those agitations and variations which the being it depends upon is subject to. The principle of all things must be immutable,616 which is described by some by a unity, the principle of number, wherein there is a resemblance of God’s unchangeableness. A unit is not variable; it continues in its own nature immutably a unit. It never varies from itself; it cannot be changed from itself; but is, as it were, so omnipotent towards others, that it changes all numbers. If you add any number, it is the beginning of that number, but the unit is not increased by it; a new number ariseth from that addition, but the unit still remains the same, and adds value to other figures, but receives none from them.

III. The third thing to speak to is, that immutability is proper to God, and incommunicable to any creature. Mutability is natural to every creature as a creature, and immutability is the sole perfection of God. He only is infinite wisdom, able to foreknow future events; he only is infinitely powerful, able to call forth all means to effect; so that wanting neither wisdom to contrive, nor strength to execute, he cannot alter his counsel. None being above him, nothing in him contrary to him, and being defective in no blessedness and perfection, he cannot vary in his essence and nature. Had not immutability as well as eternity been a property solely pertaining to the Divine nature, as well as creative power and eternal duration, the apostle’s argument to prove Christ to be God from this perpetual sameness, had come short of any convincing strength. These words of the text he applies to Christ (Heb. i. 10–12): “They shall be changed, but thou art the same.” There had been no strength in the reason, if immutability by nature did belong to any creature.

The changeableness of all creatures is evident:

1. Of corporeal creatures it is evident to sense. All plants and animals, as they have their duration bounded in certain limits; so while they do exist, they proceed from their rise to their fall. They pass through many sensible alterations, from one degree of growth to another, from buds to blossoms, from blossoms to flowers and fruits. They come to their pitch that nature had set them, and return back to the state from whence they sprung; there is not a day but they make some acquisition, or suffer some loss. They die and spring up every day; nothing in them more certain than their inconstancy: “The creature is subject to vanity” (Rom. viii. 20). The heavenly bodies are changing their place; the sun every day is running his race, and stays not in the same point; and though they are not changed in their essence, yet they are in their place. Some, indeed, say there is a continual generation of light in the sun, as there is a loss of light by the casting out its beams, as in a fountain there is a flowing out of the streams, and a continual generation of supply. And though these heavenly bodies have kept their standing and motion from the time of their creation, yet both the sun’s standing still in Joshua’s time, and its going back in Hezekiah’s time, show that they are changeable at the pleasure of God. But in man the change is perpetually visible; every day there is a change from ignorance to knowledge, from one will to another, from passion to passion, sometimes sad and sometimes cheerful, sometimes craving this, and presently nauseating it; his body changes from health to sickness, or from weakness to strength; some alteration there is either in body or mind. Man, who is the noblest creature, the subordinate end of the creation of other things, cannot assure himself of a consistency and fixedness in anything the short space of a day, no, not of a minute. All his months are months of vanity (Job vii. 3); whence the Psalmist calls man at the “best estate altogether vanity,” a mere heap of vanity (Ps. xxxv.) As he contains in his nature the nature of all creatures, so he inherits in his nature the vanity of all creatures. A little world, the centre of the world and of the vanity of the world; yea, “lighter than vanity” (Ps. lxii. 9), more movable than a feather; tossed between passion and passion, daily changing his end, and changing the means; an image of nothing.

2. Spiritual natures, as angels. They change not in their being, but that is from the indulgence of God. They change not in their goodness, but that is not from their nature, but divine grace in their confirmation; but they change in their knowledge; they know more by Christ than they did by creation (1 Tim. iii. 16). They have an addition of knowledge every day, by the providential dispensations of God to his church (Eph. iii. 10); and the increase of their astonishment and love is according to the increase of their knowledge and insight. They cannot have a new discovery without new admirations of what is discovered to them: there is a change in their joy when there is a change in a sinner (Luke xv. 10). They were changed in their essence, when they were made such glorious spirits of nothing; some of them were changed in their will, when of holy they became impure. The good angels were changed in their understandings, when the glories of God in Christ were presented to their view; and all can be changed in their essence again; and as they were made of nothing, so by the power of God may be reduced to nothing again. So glorified souls shall have an unchanged operation about God, for they shall behold his face without any grief or fear of loss, without vagrant thoughts; but they can never be unchangeable in their nature, because they can never pass from finite to infinite.

No creature can be unchangeable in its nature:—1. Because every creature rose from nothing. As they rose from nothing, so they tend to nothing, unless they are preserved by God. The notion of a creature speaks changeableness; because to be a creature is to be made something of nothing, and, therefore, creation is a change of nothing into something. The being of a creature begins from change, and, therefore, the essence of a creature is subject to change. God only is uncreated, and, therefore, unchangeable. If he were made he could not be immutable; for the very making is a change of not being into being. All creatures were made good, as they were the fruits of God’s goodness and power; but must needs be mutable, because they were the extracts of nothing. 2. Because every creature depends purely upon the will of God. They depend not upon themselves, but upon another for their being. As they received their being from the word of his mouth and the arm of his power, so by the same word they can be cancelled into nothing, and return into as little significancy as when they were nothing. He that created them by a word, can by a word destroy them: if God should “take away their breath, they die, and return into their dust” (Ps. civ. 29). As it was in the power of the Creator that things might be, before they actually were, so it is in the power of the Creator that things after they are may cease to be what they are; and they are, in their own nature, as reducible to nothing as they were producible by the power of God from nothing; for there needs no more than an act of God’s will to null them, as there needed only an act of God’s will to make them. Creatures are all subject to a higher cause: they are all reputed as nothing. “He doth according to his will in the armies of heaven, and among the inhabitants of the earth, and none can stay his hand, or say unto him, What dost thou?” (Dan. iv. 35.) But God is unchangeable, because he is the highest good; none above him, all below him; all dependent on him; himself upon none. 3. No creature is absolutely perfect. No creature can be so perfect, or can ever be, but something by the infinite power of God may be added to it; for whatsoever is finite may receive greater additions, and, therefore, a change. No creature you can imagine, but in your thoughts you may fancy him capable of greater perfections than you know he hath, or than really he hath. The perfections of all creatures are searchable; the perfection of God is only unsearchable (Job xi. 6), and, therefore, he only immutable. God only is always the same. Time makes no addition to him, nor diminisheth anything of him. His nature and essence, his wisdom and will, have always been the same from eternity, and shall be the same to eternity, without any variation.

IV. The fourth thing propounded is, Some propositions to clear this unchangeableness of God from anything that seems contrary to it.

Prop. I. There was no change in God when he began to create the world in time. The creation was a real change, but the change was not subjectively in God, but in the creature; the creature began to be what it was not before. Creation is considered as active or passive.617 Active creation is the will and power of God to create. This is from eternity, because God willed from eternity to create in time; this never had beginning, for God never began in time to understand anything, to will anything, or to be able to do anything; but he alway understood and alway willed those things which he determined from eternity to produce in time. The decree of God may be taken for the act decreeing, that is eternal and the same, or for the object decreed, that is in time; so that there may be a change in the object, but not in the will whereby the object doth exist.

1. There was no change in God by the act of creation, because there was no new will in him. There was no new act of his will which was not before. The creation began in time, but the will of creating was from eternity. The work was new, but the decree whence that new work sprung was as ancient as the Ancient of Days. When the time of creating came, God was not made ex nolente volens, as we are; for whatsoever God willed to be now done, he willed from eternity to be done; but he willed also that it should not be done till such an instant of time, and that it should not exist before such a time. If God had willed the creation of the world only at that time when the world was produced, and not before, then, indeed, God had been changeable. But though God spake that word which he had not spoke before, whereby the world was brought into act; yet he did not will that will he willed not before. God did not create by a new counsel or new will, but by that which was from eternity (Eph. i. 9). All things are wrought according to that “purpose in himself,” and according to “the counsel of his will” (ver. 11); and as the holiness of the elect is the fruit of his eternal will “before the foundation of the world” (ver. 4), so, likewise, is the existence of things, and of those persons whom he did elect. As when an artificer frames a house or a temple according to that model he had in his mind some years before, there is no change in the model in his mind; the artificer is the same, though the work is produced by him some time after he had framed that copy of it in his own mind, but there is a change of the thing produced by him according to that model. Or, when a rich man intends, four or five years hence, if he lives, to build a hospital, is there any change in will, when, after the expiration of that time, he builds and endows it? Though it be after his will, yet it is the fruit of his precedent will. So God, from all eternity, did will and command that the creatures should exist in such a part of time; and, by his eternal will, all things, whether past, present, or to come, did, do, and shall exist, at that point of time which that will did appoint for them: not, as though God had a new will when things stood up in being, but only that which was prepared in his immutable counsel and will from eternity, doth then appear. There can be no instant fixed from eternity, wherein it can be said, God did not will the creation of the world; for had the will of God for the shortest moment been undetermined to the creation of the world, and afterwards resolved upon it, there had been a moral change in God from not willing to willing; but this there was not, for God executes nothing in time which he had not ordained from eternity, and appointed all the means and circumstances whereby it should be brought about. As the determination of our Saviour to suffer was not a new will, but an eternal counsel, and wrought no change in God (Acts ii. 23).

2. There is no change in God by the act of creation, because there was no new power in God. Had God had a will at the time of creation which he had not before, there had been a moral change in him; so had there been in him a power only to create then and not before, there had been a physical change in him from weakness to ability. There can be no more new power in God, than there can be a new will in God; for his will is his power, and what he willeth to effect, that he doth effect: as he was unchangeably holy, so he was unchangeably almighty, “which was, and is, and is to come” (Rev. iv. 8); which was almighty, and is almighty, and ever will be almighty. The work therefore makes no change in God, but there is a change in the thing wrought by that power of God. Suppose you had a seal engraven upon some metal a hundred years old, or as old as the creation, and you should this day, so many ages after the engraving of it, make an impression of that seal upon wax; would you say the engravement upon the seal were changed, because it produced that stamp upon the wax now which it did not before? No, the change is purely in the wax, which receives a new figure or form by the impression; not in the seal, that was capable of imprinting the same long before. God was the same from eternity as he was when he made a signature of himself upon the creatures by creation, and is no more changed by stamping them into several forms, than the seal is changed by making impression upon the wax. As when a house is enlightened by the sun, or that which was cold is heated by it, there is a change in the house from darkness to light, from coldness to heat; but is there any change in the light and heat of the sun? There is a change in the thing enlightened or warmed by that light and heat which remains fixed and constant in the sun, which was as capable in itself to produce the same effects before, as at that instant when it works them; so when God is the author of a new work, he is not changed, because he works it by an eternal will and an eternal power.

3. Nor is there any new relation acquired by God by the creation of the world. There was a new relation acquired by the creature, as, when a man sins, he hath another relation to God than he had before,—he hath relation to God, as a criminal to a Judge; but there is no change in God, but in the malefactor. The being of men makes no more change in God than the sins of men. As a tree is now on our right hand, and by our turning about it is on our left hand, sometimes before us, sometimes behind us, according to our motion near it or about it, and the turning of the body; there is no change in the tree, which remains firm and fixed in the earth, but the change is wholly in the posture of the body, whereby the tree may be said to be before us or behind us, or on the right hand or on the left hand.618 God gained no new relation of Lord or Creator by the creation; for though he had created nothing to rule over, yet he had the power to create and rule, though he did not create and rule: as a man may be called a skilful writer, though he does not write, because he is able to do it when he pleases; or a man skilful in physic is called a physician, though he doth not practise that skill, or discover his art in the distribution of medicines, because he may do it when he pleases; it depends upon his own will to show his art when he has a mind to it. So the name Creator and Lord belongs to God from eternity, because he could create and rule, though he did not create and rule. But, howsoever, if there were any such change of relation, that God may be called Creator and Lord after the creation and not before, it is not a change in essence, nor in knowledge, nor in will; God gains no perfection nor diminution by it; his knowledge is not increased by it; he is no more by it than he was, and will be, if all those things ceased; and therefore Austin illustrates it by this similitude:—as a piece of money when it is given as the price of a thing, or deposited only as a pledge for the security of a thing borrowed; the coin is the same, and is not changed, though the relation it had as a pledge and as a price be different from one another: so that suppose any new relation be added, yet there is nothing happens to the nature of God which may infer any change.

Prop. II. There was no change in the Divine nature of the Son, when he assumed human nature. There was an union of the two natures, but no change of the Deity into the humanity, or of the humanity into the Deity: both preserved their peculiar properties. The humanity was changed by a communication of excellent gifts from the divine nature, not by being brought into an equality with it, for that was impossible that a creature should become equal to the Creator. He took the “form of a servant,” but he lost not the form of God; he despoiled not himself of the perfections of the Deity. He was indeed emptied, “and became of no reputation” (Phil. ii. 7); but he did not cease to be God, though he was reputed to be only a man, and a very mean one too. The glory of his divinity was not extinguished nor diminished, though it was obscured and darkened, under the veil of our infirmities; but there was no more change in the hiding of it, than there is in the body of the sun when it is shadowed by the interposition of a cloud. His blood while it was pouring out from his veins was the “blood of God” (Acts xx. 28); and, therefore, when he was bowing the head of his humanity upon the cross, he had the nature and perfections of God; for had he ceased to be God, he had been a mere creature, and his sufferings would have been of as little value and satisfaction as the sufferings of a creature. He could not have been a sufficient Mediator, had he ceased to be God: and he had ceased to be God, had he lost any one perfection proper to the divine nature; and losing none, he lost not this of unchangeableness, which is none of the meanest belonging to the Deity. Why by his union with the human nature should he lose this, any more than he lost his omniscience, which he discovered by his knowledge of the thoughts of men; or his mercy, which he manifested to the height in the time of his suffering? That is truly a change, when a thing ceaseth to be what it was before: this was not in Christ; he assumed our nature without laying aside his own. When the soul is united to the body, doth it lose any of those perfections that are proper to its nature? Is there any change either in the substance or qualities of it? No; but it makes a change in the body, and of a dull lump it makes it a living mass, conveys vigor and strength to it, and, by its power, quickens it to sense and motion.619 So did the divine nature and human remain entire; there was no change of the one into the other, as Christ by a miracle changed water into wine, or men by art change sand or ashes into glass: and when he prays “for the glory he had with God before the world was” (John xvii. 5), he prays that a glory he had in his Deity might shine forth in his person as Mediator, and be evidenced in that height and splendor suitable to his dignity, which had been so lately darkened by his abasement; that as he had appeared to be the Son of Man in the infirmity of the flesh, he might appear to be the Son of God in the glory of his person, that he might appear to be the Son of God and the Son of Man in one person.620 Again, there could be no change in this union; for, in a real change, something is acquired which was not possessed before, neither formally nor eminently: but the divinity had from eternity, before the incarnation, all the perfections of the human nature eminently in a nobler manner than they are in themselves, and therefore could not be changed by a real union.621

Prop. III. Repentance and other affections ascribed to God in Scripture, argue no change in God. We often read of God’s repenting, repenting of the good he promised (Jer. xviii. 10), and of the evil he threatened (Exod. xxxii. 14; John iii. 10), or of the work he hath wrought (Gen. vi. 6). We must observe, therefore, that,

1. Repentance is not properly in God. He is a pure Spirit, and is not capable of those passions which are signs of weakness and impotence, or subject to those regrets we are subject to. Where there is a proper repentance there is a want of foresight, an ignorance of what would succeed, or a defect in the examination of the occurrences which might fall within consideration. All repentance of a fact is grounded upon a mistake in the event which was not foreseen, or upon an after knowledge of the evil of the thing which was acted by the person repenting. But God is so wise that he cannot err, so holy he cannot do evil; and his certain prescience, or foreknowledge, secures him against any unexpected events. God doth not act but upon clear and infallible reason; and a change upon passion is accounted by all so great a weakness in man, that none can entertain so unworthy a conceit of God. Where he is said to repent (Gen. vi. 6), he is also said to grieve; now no proper grief can be imagined to be in God. As repentance is inconsistent with infallible foresight, so is grief no less inconsistent with undefiled blessedness. God is “blessed forever” (Rom. ix. 8), and therefore nothing can befall him that can stain that blessedness. His blessedness would be impaired and interrupted while he is repenting, though he did soon rectify that which is the cause of his repentance. “God is of one mind, and who can turn him? what his soul desires that he doth” (Job xxiii. 13).

2. But God accommodates himself in the Scripture to our weak capacity. God hath no more of a proper repentance, than he hath of a real body; though he, in accommodation to our weakness, ascribes to himself the members of our bodies to set out to our understanding the greatness of his perfections, we must not conclude him a body like us; so, because he is said to have anger and repentance, we must not conclude him to have passions like us. When we cannot fully comprehend him as he is, he clothes himself with our nature in his expressions that we may apprehend him as we are able, and by an inspection into ourselves, learn something of the nature of God; yet those human ways of speaking ought to be understood in a manner agreeable to the infinite excellency and majesty of God, and are only designed to mark out something in God which hath a resemblance with something in us; as we cannot speak to God as gods, but as men, so we cannot understand him speaking to us as a God, unless he condescend to speak to us like a man. God therefore frames his language to our dulness, not to his own state, and informs us by our own phrases, what he would have us learn of his nature, as nurses talk broken language to young children. In all such expressions, therefore, we must ascribe the perfection we conceive in them to God, and lay the imperfection at the door of the creature.

3. Therefore, repentance in God is only a change of his outward conduct, according to his infallible foresight and immutable will. He changes the way of his providential proceeding according to the carriage of the creature, without changing his will, which is the rule of his providence. When God speaks of his repenting “that he had made man” (Gen. vi. 6), it is only his changing his conduct from a way of kindness to a way of severity, and is a word suited to our capacities to signify his detestation of sin, and his resolution to punish it, after man had made himself quite another thing, than God had made him; “it repents me,” that is, I am purposed to destroy the world, as he that repents of his work throws it away;622 as if a potter cast away the vessel he had framed, it were a testimony that he repented that ever he took pains about it, so the destruction of them seems to be a repentance in God that ever he made them; it is a change of events, not of counsels. Repentance in us is a grief for a former fact, and a changing of our course in it; grief is not in God, but his repentance is a willing a thing should not be as it was, which will was fixed from eternity; for God, foreseeing man would fall, and decreeing to permit it, he could not be said to repent in time of what he did not repent from eternity; and therefore, if there were no repentance in God from eternity, there could be none in time.623 But God is said to repent when he changes the disposition of affairs without himself; as men, when they repent, alter the course of their actions, so God alters things, extra se, or without himself, but changes nothing of his own purpose within himself. It rather notes the action he is about to do, than anything in his own nature, or any change in his eternal purpose. God’s repenting of his kindness is nothing but an inflicting of punishment, which the creature by the change of his carriage hath merited: as his repenting of the evil threatened is the withholding the punishment denounced, when the creature hath humbly submitted to his authority, and acknowledged his crime. Or else we may understand those expressions of joy, and grief, and repentance, to signify thus much, that the things declared to be the objects of joy, and grief, and repentance, are of that nature, that if God were capable of our passions, he would discover himself in such cases as we do; as when the prophets mention the joys and applaudings of heaven, earth, and the sea, they only signify that the things they speak of are so good, that if the heavens and the sea had natures capable of joy, they would express it upon that occasion in such a manner as we do; so would God have joy at the obedience of men, and grief at the unworthy carriage of men, and repent of his kindness when men abuse it, and repent of his punishment when men reform under his rod, were the majesty of his nature capable of such affections.624

Prop. IV. The not fulfilling of some predictions in Scripture, which seem to imply a changeableness of the Divine will, do not argue any change in it. As when he reprieved Hezekiah from death, after a message sent by the prophet Isaiah, that he should die (2 Kings xx. 1–5; Isa. xxxviii. 1–5), and when he made an arrest of that judgment he had threatened by Jonah against Nineveh (Jon. iii. 4–10). There is not, indeed, the same reason of promises and threatenings altogether; for in promising, the obligation lies upon God, and the right to demand is in the party that performs the condition of the promise: but in threatenings, the obligation lies upon the sinner, and God’s right to punish is declared thereby; so that though God doth not punish, his will is not changed, because his will was to declare the demerit of sin, and his right to punish upon the commission of it; though he may not punish according to the strict letter of the threatening the person sinning, but relax his own law for the honor of his attributes, and transfer the punishment from the offender to a person substituted in his room: this was the case in the first threatening against man, and the substituting a Surety in the place of the malefactor. But the answer to these cases is this, that where we find predictions in Scripture declared, and yet not executed, we must consider them, not as absolute but conditional, or as the civil law calls it, an interlocutory sentence.625 God declared what would follow by natural causes, or by the demerit of man, not what he would absolutely himself do: and in many of those predictions, though the condition be not expressed, yet it is to be understood; so the promises of God are to be understood, with the condition of perseverance in well doing; and threatenings, with a clause of revocation annexed to them, provided that men repent: and this God lays down as a general case, alway to be remembered as a rule for the interpreting his threatenings against a nation, and the same reason will hold in threatenings against a particular person. (Jer. xviii. 7–10) “At what instant I shall speak concerning a nation, and concerning a kingdom, to pluck up, and to pull down, and destroy it; if that nation, against whom I have pronounced, turn from their evil, I will repent of the evil that I thought to do unto them;” and so when he speaks of planting a nation, if they do evil, he will repent of the good, &c. It is a universal rule by which all particular cases of this nature are to be tried; so that when man’s repentance arrives, God remains firm in his first will, always equal to himself; and it is not he that changes, but man. For since the interposition of the Mediator, with an eye to whom God governed the world after the fall, the right of punishing was taken off if men repented, and mercy was to flow out, if by a conversion men returned to their duty (Ezek. xviii. 20, 21). This, I say, is grounded upon God’s entertaining the Mediator; for the covenant of works discovered no such thing as repentance or pardon. Now these general rules are to be the interpreters of particular cases: so that predictions of good are not to be counted absolute, if men return to evil; nor predictions of evil, if men be thereby reduced to a repentance of their crimes. So Nineveh shall be destroyed, that is, according to the general rule, unless the inhabitants repent, which they did; they manifested a belief of the threatening, and gave glory to God by giving credit to the prophet: and they had a notion of this rule God lays down in the other prophets; for they had an apprehension that, upon their humbling themselves, they might escape the threatened vengeance, and stop the shooting those arrows that were ready in the bow.626 Though Jonah proclaimed destruction without declaring any hopes of an arrest of judgment, yet their natural notion of God afforded some natural hopes of relief if they did their duty, and spurned not against the prophet’s message; and therefore, saith one, God did not always express this condition, because it was needless; his own rule revealed in Scripture was sufficient to some; and the natural notion all men had of God’s goodness upon their repentance, made it not absolutely necessary to declare it. And besides, saith he, it is bootless; the expressing it can do but little good; secure ones will repent never the sooner, but rather presume upon their hopes of God’s forbearance, and linger out their repentance till it be too late. And to work men to repentance, whom he hath purposed to spare, he threatens them with terrible judgments; which by how much the more terrible and peremptory they are, are likely to be more effectual for that end God in his purpose designs them; viz. to humble them under a sense of their demerit, and an acknowledgment of his righteous justice; and, therefore, though they be absolutely denounced, yet they are to be conditionally interpreted with a reservation of repentance. As for that answer which one gives, that by forty days was not meant forty natural days, but forty prophetical days, that is years, a day for a year; and that the city was destroyed forty years after by the Medes; the expression of God’s repenting upon their humiliation puts a bar to that interpretation; God repented, that is, he did not bring the punishment upon them according to those days the prophet had expressed; and, therefore, forty natural days are to be understood; and if it were meant forty years, and they were destroyed at the end of that term, how could God be said to repent, since according to that, the punishment threatened was, according to the time fixed, brought upon them? and the destruction of it forty years after will not be easily evinced, if Jonah lived in the time of Jeroboam, the second king of Israel, as he did (2 Kings xiv. 25); and Nineveh was destroyed in the time of Josiah, king of Judah. But the other answer is plain. God did not fulfil what he had threatened, because they reformed what they had committed: when the threatening was made, they were a fit object for justice; but when they repented, they were a fit object for a merciful respite. To threaten when sins are high, is a part of God’s justice; not to execute when sins are revoked by repentance, is a part of God’s goodness. And in the case of Hezekiah (2 Kings xx. 1, 5), Isaiah comes with a message from God, that he should “set his house in order,” for he shall die; that is, the disease was mortal, and no outward applications could in their own nature resist the distemper: “Behold, I will add to thy days fifteen years; I will heal thee” (Isa. xxxviii. 1, 5). It seems to me to be one entire message, because the latter part of it was so suddenly after the other committed to Isaiah, to be delivered to Hezekiah; for he was not gone out of the king’s house, before he was ordered to return with the news of his health, by an extraordinary indulgence of God against the power of nature and force of the disease, “Behold, I will add to thy life;” noting it as an extraordinary thing; he was in the second court of the king’s house when this word came to him (2 Kings xx. 4); the king’s house having three courts, so that he was not gone above half‑way out of the palace. God might send this message of death, to prevent the pride Hezekiah might swell with for his deliverance from Sennacherib: as Paul had a messenger of Satan to buffet him to prevent his lifting up (2 Cor. xii. 7); and this good man was subject to this sin, as we find afterwards in the case of the Babylonish ambassadors; and God delayed this other part of the message to humble him, and draw out his prayer: and as soon as ever he found Hezekiah in this temper, he sent Isaiah with a comfortable message of recovery; so that the will of God was to signify to him the mortality of his distemper, and afterwards to relieve him by a message of an extraordinary recovery.

Prop. V. God is not changed, when of loving to any creatures he becomes angry with them, or of angry he becomes appeased. The change in these cases is in the creature; according to the alteration in the creature, it stands in a various relation to God: an innocent creature is the object of his kindness, an offending creature is the object of his anger; there is a change in the dispensations of God, as there is a change in the creature making himself capable of such dispensations. God always acts according to the immutable nature of his holiness, and can no more change in his affections to good and evil, than he can in his essence. When the devils, now fallen, stood as glorious angels, they were the objects of God’s love, because holy; when they fell, they were the objects of God’s hatred, because impure; the same reason which made him love them while they were pure, made him hate them when they were criminal. The reason of his various dispensations to them was the same in both, as considered in God, his immutable holiness; but as respecting the creature, different; the nature of the creature was changed, but the Divine holy nature of God remained the same: “With the pure thou wilt show thyself pure, and with the froward, thou wilt show thyself froward” (Ps. xviii. 26): he is a refreshing light to those that obey him, and a consuming fire to those that resist him. Though the same angels were not always loved, yet the same reason that moved him to love them, moved him to hate them. It had argued a change in God if he had loved them alway, in whatsoever posture they were towards him; it could not be counted love, but a weakness and impotent fondness; the change is in the object, not in the affection of God; for the object loved before is not beloved now, because that which was the motive of love, is not now in it; so that the creature having a different state from what it had, falls under a different affection or dispensation. It had been a mutable affection in God to love that which was not worthy of love with the same love wherewith he loved that which had the greatest resemblance to himself; had God loved the fallen angels in that state and for that state, he had hated himself, because he had loved that which was contrary to himself and the image of his own holiness, which made them appear before, good in his sight. The will of God is unchangeably set to love righteousness and hate iniquity, and from this hatred to punish it; and if a righteous creature contracts the wrath of God, or a sinful creature hath the communications of God’s love, it must be by a change in themselves. Is the sun changed when it hardens one thing and softens another, according to the disposition of the several subjects? Or when the sun makes a flower more fragrant, and a dead carcass more noisome? There are divers effects, but the reason of that diversity is not in the sun, but in the subject; the sun is the same, and produceth those different effects by the same quality of heat; so if an unholy soul approach to God, God looks angrily upon him; if a holy soul come before him, the same immutable perfection in God draws out his kindness towards him: as some think, the sun would rather refresh than scorch us, if our bodies were of the same nature and substance with that luminary. As the will of God for creating the world was no new, but an eternal will, though it manifested itself in time, so the will of God for the punishment of sin, or the reconciliation of the sinner, was no new will: though his wrath in time break out in the effects of it upon sinners, and his love flows out in the effects of it upon penitents. Christ by his death reconciling God to man, did not alter the will of God, but did what was consonant to his eternal will; he came not to change his will, but to execute his will: “Lo, I come to do thy will, O God” (Heb. x. 7). And the grace of God in Christ was not a new grace, but an old grace in a new appearance; “the grace of God hath appeared” (Tit. i. 11).

Prop. VI. A change of laws by God argues no change in God, when God abrogates some laws which he had settled in the church, and enacts others. I spake of this something the last day; I shall only add this: God commanded one thing to the Jews, when the church was in an infant state; and removed those laws, when the church came to some growth. The elements of the world were suited to the state of children (Gal. iv. 3). A mother feeds not the infant with the same diet as she doth when it is grown up. Our Saviour acquainted not his disciples with some things at one time which he did at another, because they were not able to bear them: where was the change; in Christ’s will, or in their growth from a state of weakness to that of strength? A physician prescribes not the same thing to a person in health, as he doth to one conflicting with a distemper; nor the same thing in the beginning as he doth in the state or declination of the disease. The physician’s will and skill are the same, but the capacity and necessity of the patient for this or that medicine, or method of proceeding, are not the same. When God changed the ceremonial law, there was no change in the Divine will, but an execution of his will; for when God commanded the observance of the law he intended not the perpetuity of it; nay, in the prophets he declares the cessation of it; he decreed to command it, but he decreed to command it only for such a time; so that the abrogation of it was no less an execution of his decree, than the establishment of it for a season was; the commanding of it was pursuant to his decree for the appointing of it, and the nulling of it was pursuant to his decree of continuing it only for such a season; so that in all this there was no change in the will of God. The counsel of God stands sure; what changes soever there are in the world, are not in God or his will, but in the events of things, and the different relations of things to God: it is in the creature, not in the Creator. The sun alway remains of the same hue, and is not discolored in itself, because it shines green through a green glass, and blue through a blue glass; the different colors come from the glass, not from the sun; the change is alway in the disposition of the creature, and not in the nature of God or his will.

V. Use 1. For information.

1. If God be unchangeable in his nature, and immutability be a property of God, then Christ hath a Divine nature. This in the Psalm is applied to Christ in the Hebrews (Heb. i. 11), where he joins the citation out of this Psalm with that out of Ps. xlv. 6, 7, “Thy throne, O God, is forever and ever; thou hast loved righteousness and hated iniquity; therefore God, even thy God, hath anointed thee with the oil of gladness above thy fellows; and thou, Lord, in the beginning hast laid the foundation of the earth,” &c. As the first must necessarily be meant of Christ the Mediator, and therein he is distinguished from God, as one anointed by him; so the other must be meant of Christ, whereby he is made one with God in regard of the creation and dissolution of the world, in regard of eternity and immutability. Both the testimonies are linked together by the copulative and, “and thou, Lord;” declaring thereby that they are both to be understood of the same person, the Son of God. The design of the chapter is to prove Christ to be God; and such things are spoken of him as could not belong to any creature; no, not to the most excellent of the angels. The same person that is said to be anointed above his fellows, and is said to lay the foundation of the earth and heavens, is said to be the same; that is, the same in himself; the prerogative of sameness belongs to that person as well as creation of heaven and earth. The Socinians say it is spoken of God, and that God shall destroy the heavens by Christ; if so, Christ is not a mere creature, not created when he was incarnate; for the same person that shall change the world did create the world; if God shall change the world by him, God also created the world by him; he was then before the world was; for how could God create the world by one that was not; that was not in being till after the creation of the world? The heavens shall be changed, but the person who is to change the heavens is said to be the same, or unchangeable in the creation as well as the dissolution of the world. This sameness refers to the whole sentence. The Psalm wherein the text is, and whence this in the Hebrews is cited, is properly meant of Christ, and redemption by him, and the completing of it at the last day, and not of the Babylonish captivity;627 that captivity was not so deplorable as the state of the Psalmist describes; Daniel and his companions flourished in that captivity; it could not reasonably be said of them, that their days were consumed like smoke, their hearts withered like grass; that they forgot to “eat their bread” (ver. 3, 4). Besides, he complains of “shortness of life” (ver. 11); but none had any more reason to complain of that in the time of the captivity, than before and after it, than at any other time: their deliverance would contribute nothing to the natural length of their lives. Besides, when Sion should be built, the heathen should “fear the name of the Lord” (that is, worship God), and “all the kings of the earth his glory” (ver. 15). The rearing the second temple after the deliverance, did not proselyte the nations; nor did the kings of the earth worship the glory of God; nor did God appear in such glory at the erecting the second temple. The second temple was less glorious than the first, for it wanted some of the ornaments which were the glory of the first; but it is said of this state, that when the Lord should build up Sion, he should “appear in his glory” (ver. 16); his proper glory, and extraordinary glory. Now that God who shall appear in glory, and build up Sion, is the Son of God, the Redeemer of the world; he builds up the church, he causes the nations to fear the Lord, and the kings of the earth his glory; he broke down the partition wall, and opened a door for the entrance of the Gentiles; he struck the chains from off the prisoners, and loosed those that were appointed to death by the curse of the law (ver. 20): and to this person is ascribed the creation of the world; and he is pronounced to remain the same in the midst of an infinite number of changes in inferior things. And it is likely the Psalmist considers not only the beginning of redemption, but the completing of it at the second coming of Christ; for he complains of those evils which shall be removed by his second coming, viz., the shortness of life, persecutions and reproaches wherewith the church is afflicted in this world; and comforts not himself with those attributes which are directly opposed to sin, as the mercy of God, the covenant of God, but with those that are opposed to mortality and calamities, as the unchangeableness and eternity of God; and from thence infers a perpetual establishment of believers. “The children of thy servants shall continue, and their seed shall be established before thee” (ver. 28): so that the Psalm itself seems to aim in the whole discourse at Christ, and asserts his divinity, which the apostle, as an interpreter, doth fully evidence; applying it to him, and manifesting his deity by his immutability as well as eternity.628 While all other things lose their forms, and pass through multitudes of variations, he constantly remains the same, and shall be the same, when all the empires of the world shall slide away, and a period be put to the present motions of the creation: and as there was no change made in his being by the creation of things, so neither shall there be by the final alteration of things; he shall see them finish, as he saw them rise up into being, and be the same after their reign, as he was before their original; he is the first and the last (Rev. i. 17).

2. Here is ground and encouragement for worship. An atheist will make another use of this; if God be immutable, why should we worship him, why should we pray to him? good will come if he wills it; evil cannot be averted by all our supplications, if he hath ordained it to fall upon us. But certainly since unchangeableness is knowing, and willing goodness is a perfection, an adoration and admiration is due to God, upon the account of this excellence. If he be God, he is to be reverenced, and the more highly reverenced, because he cannot but be God. Again, what comfort could it be to pray to a God, that like the chameleon changed colors every day, every moment? What encouragement could there be to lift up our eyes to one that were of one mind this day and of another mind tomorrow? Who would put up a petition to an earthly prince that were so mutable, as to grant a petition one day and deny it another, and change his own act? But if a prince promise this or that thing upon such or such a condition, and you know his promise to be as unchangeable as the laws of the Medes and Persians, would any man reason thus? because it is unchangeable we will not seek to him, we will not perform the condition, upon which the fruit of the proclamation is to be enjoyed. Who would not count such an inference ridiculous? What blessings hath not God promised upon the condition of seeking him? Were he of an unrighteous nature, or changeable in his mind, this would be a bar to our seeking him, and frustrate our hopes; but since it is otherwise, is not this excellency of his nature the highest encouragement, to ask of him the blessings he hath promised, and a beam from heaven to fire our zeal in asking? If you desire things against his will, which he hath declared he will not grant, prayer then would be an act of disobedience and injury to him, as well as an act of folly in itself; his unchangeableness then might stifle such desires: but if we ask according to his will, and according to our reasonable wants, what ground have we to make such a ridiculous argument? He hath willed everything that may be for our good, if we perform the condition he hath required; and hath put it upon record, that we may know it and regulate our desires and supplications according to it. If we will not seek him, his immutability cannot be a bar, but our own folly is the cause; and by our neglect we despoil him of this perfection as to us, and either imply that he is not sincere, and means not as he speaks; or that he is as changeable as the wind, sometimes this thing, sometimes that, and not at all to be confided in. If we ask according to his revealed will, the unchangeableness of his nature will assure us of the grant; and what a presumption would it be in a creature dependent upon his sovereign, to ask that which he knows he has declared his will against; since there is no good we can want, but he hath promised to give, upon our sincere and ardent desire for it? God hath decreed to give this or that to man, but conditionally, and by the means of inquiring after him, and asking for it: “Ask, and you shall receive” (Ezek. xxxvi. 37; Matt. vii. 7): as much as to say, You shall not receive unless you ask. When the highest promises are made, God expects they should be put in suit; our Saviour joins the promise and the petition together; the promise to encourage the petition, and the petition to enjoy the promise: he doth not say perhaps it shall be given, but it shall, that is, it certainly shall; your heavenly Father is unchangeably willing to give you those things. We must depend upon his immutability for the thing, and submit to his wisdom for the time. Prayer is an acknowledgment of our dependence upon God; which dependence could have no firm foundation without unchangeableness. Prayer doth not desire any change in God, but is offered to God that he would confer those things which he hath immutably willed to communicate; but he willed them not without prayer as the means of bestowing them. The light of the sun is ordered for our comfort, for the discovery of visible things, for the ripening the fruits of the earth; but withal it is required that we use our faculty of seeing, that we employ our industry in sowing and planting, and expose our fruits to the view of the sun, that they may receive the influence of it. If a man shuts his eyes, and complains that the sun is changed into darkness, it would be ridiculous; the sun is not changed, but we alter ourselves; nor is God changed in not giving us the blessings he hath promised, because he hath promised in the way of a due address to him, and opening our souls to receive his influence, and to this, his immutability is the greatest encouragement.

3. This shows how contrary man is to God in regard of his inconstancy. What an infinite distance is there between the immutable God, and mutable man, and how should we bewail this flittingness in our nature! There is a mutability in us as creatures, and a creature cannot but be mutable by nature, otherwise it were not a creature but God. The establishment of any creature is from grace and gift; naturally we tend to nothing, as we come from nothing. This creature‑mutability is not our sin, yet it should cause us to lie down under a sense of our own nothingness, in the presence of the Creator. The angels as creatures, though not corrupt, cover their faces before him: and the arguments God uses to humble Job, though a fallen creature, are not from his corruption: for I do not remember that he taxed him with that; but from the greatness of his majesty and excellency of his nature declared in his works (Job xxxviii.–xli.); and, therefore, men that have no sense of God and humility before him, forget that they are creatures as well as corrupt ones. How great is the distance between God and us, in regard of our inconstancy in good, which is not natural to us by creation: for the mind and affections were regular, and by the great artificer were pointed to God as the object of knowledge and love. We have the same faculties of understanding, will, and affection, as Adam had in innocence; but not with the same light, the same bias, and the same ballast. Man, by his fall, wounded his head and heart; the wound in his head made him unstable in the truth, and that in his heart unsteadfast in his affections: he changed himself from the image of God to that of the devil, from innocence to corruption, and from an ability to be steadfast to a perpetual inconstancy; “his silver became dross, and his wine was mixed with water” (Isa. i. 22). He changed,

(1.) To inconstancy in truth, opposed to the immutability of knowledge in God. How are our minds floating between ignorance and knowledge! Truth in us is like those ephemera, creatures of a day’s continuance,—springs up in the morning, and expires at night. How soon doth that fly away from us which we have had, not only some weak flashes of, but which we have learned and have had some relish of! The devil stood not in the truth (John viii. 44), and therefore manages his engines to make us as unstable as himself: our minds reel, and corrupt reasonings oversway us; like sponges we suck up water, and a light compression makes us spout it out again. Truths are not engraven upon our hearts, but writ as in dust, defaced by the next puff of wind, “carried about with every wind of doctrine” (Eph. iv. 14); like a ship without a pilot and sails, at the courtesy of the next storm, or like clouds that are tenants to the wind and sun, moved by the wind and melted by the sun. The Galatians were no sooner called into the grace of God, but they were removed from it (Gal. i. 6); some have been reported to have menstruam fidem, kept an opinion for a month; and many are like him that believed the soul’s immortality no longer than he had Plato’s book of that subject in his hand:629 one likens such to children; they play with truths as children do with babies, one while embrace them, and a little after throw them into the dirt. How soon do we forget what the truth is delivered to us, and what it represented us to be (James i. 23, 24). Is it not a thing to be bewailed, that man should be such a weathercock, turned about with every breath of wind, and shifting aspects as the wind shifts points?

(2.) Inconstancy in will, and affections opposed to the immutability of will in God. We waver between God and Baal; and while we are not only resolving, but upon motion a little way, look back with a hankering after Sodom; sometimes lifted up with heavenly intentions, and presently cast down with earthly cares, like a ship that by an advancing wave seems to aspire to heaven, and the next fall of the waves makes it sink down to the depths. We change purposes oftener than fashions, and our resolutions are like letters in water, whereof no mark remains; we will be as John to‑day to love Christ, and as Judas to‑morrow to betray him, and, by an unworthy levity, pass into the camp of the enemies of God; resolved to be as holy as angels in the morning, when the evening beholds us as impure as devils. How often do we hate what before we loved, and shun what before we longed for! and our resolutions are like vessels of crystal, which break at the first knock, are dashed in pieces by the next temptation. Saul resolved not to persecute David any more, but you soon find him upon his old game. Pharaoh more than once promised, and probably resolved, to let Israel go, but at the end of the storm his purposes vanish (Exod. viii. 27, 32). When an affliction pincheth men, they intend to change their course, and the next news of ease changes their intentions; like a bow not fully bent in their inclinations, they cannot reach the mark, but live many years between resolutions of obedience and affections to rebellion (Ps. lxxviii. 17): and what promises men make to God are often the fruit of their passion, their fear, not of their will. The Israelites were startled at the terrors wherewith the law was delivered, and promised obedience (Exod. xx. 19), but a month after forgot them, and make a golden calf, and in the sight of Sinai call for, and dance before, their gods (Exod. xxxii.); never people more unconstant. Peter, who vowed an allegiance to his Master, and a courage to stick to him, forswears him almost with the same breath. Those that cry out with a zeal, “The Lord he is God,” shortly after return to the service of their idols (1 Kings xviii. 39). That which seems to be our pleasure this day, is our vexation to‑morrow; a fear of a judgment puts us into a religious pang, and a love to our lusts reduceth us to a rebellious inclination; as soon as the danger is over, the saint is forgotten: salvation and damnation present themselves to us, touch us, and engender some weak wishes, which are dissolved by the next allurements of a carnal interest. No hold can be taken of our promises, no credit is to be given to our resolutions.

(3.) Inconstancy in practice. How much beginning in the Spirit, and ending in the flesh; one day in the sanctuary, another in the stews; clear in the morning as the sun, and clouded before noon; in heaven by an excellency of gifts, in hell by a course of profaneness; like a flower, which some mention, that changes its color three times a day, one part white, then purple, then yellow! The spirit lusts against the flesh, and the flesh quickly triumphs over the spirit. In a good man how often is there a spiritual lethargy; though he doth not openly defame God, yet he doth not always glorify him; he doth not forsake the truth, but he doth not always make the attainment of it, and settlement in it his business. This levity discovers itself in religious duty, “when I would do good, evil is present with me” (Rom. vii. 21). Never more present, than when we have a mind to do good, and never more present than when we have a mind to do the best and greatest good. How hard is it to make our thoughts and affections keep their stand! place them upon a good object, and they will be frisking from it, as a bird from one bough, one fruit, to another: we vary postures according to the various objects we meet with. The course of the world is a very airy thing, suited to the uncertain notions of that “prince of the power of the air,” which works in it (Eph. ii. 2). This ought to be bewailed by us. Though we may stand fast in the truth, though we may spin our resolutions into a firm web, though the spirit may triumph over the flesh in our practice, yet we ought to bewail it, because inconstancy is our nature, and what fixedness we have in good is from grace. What we find practised by most men is natural to all;630 “as face answers to face in a glass, so doth heart to heart” (Prov. xxvii. 19); a face in the glass is not more like a natural face, whose image it is, than one man’s heart is naturally like another.

1st. It is natural to those out of the church. Nebuchadnezzar is so affected with Daniel’s prophetic spirit, that he would have none accounted the true God, but the “God of Daniel” (Dan. ii. 47). How soon doth this notion slip from him, and an image must be set up for all to worship, upon pain of a most cruel, painful death! Daniel’s God is quite forgotten. The miraculous deliverance of the three children, for not worshipping his image, makes him settle a decree to secure the honor of God from the reproach of his subjects (Dan. iii. 29); yet, a little while after, you have him strutting in his palace, as if there were no God but himself.

2d. It is natural to those in the Church. The Israelites were the only church God had in the world, and a notable example of inconstancy. After the miracles of Egypt, they murmured against God, when they saw Pharaoh marching with an army at their heels. They desired food, and soon nauseated the manna they were before fond of. When they came into Canaan, they sometimes worshipped God, and sometimes idols, not only the idols of one nation, but of all their neighbors. In which regard God calls this, his heritage; “a speckled bird” (Jer. xii. 9); a peacock, saith Hierom, inconstant, made up of varieties of idolatrous colors and ceremonies. This levity of spirit is the root of all mischief; it scatters our thoughts in the service of God; it is the cause of all revolts and apostasies from him; it makes us unfit to receive the communications of God: whatsoever we hear is like words writ in sand, ruffled out by the next gale; whatsoever is put into us is like precious liquor in a palsy hand, soon spilt: it breeds distrust of God when we have an uncertain judgment of him, we are not like to confide in him; an uncertain judgment will be followed with a distrustful heart. In fine, where it is prevalent, it is a certain sign of ungodliness. To be driven with the wind like chaff, and to be ungodly, is all one in the judgment of the Holy Ghost (Ps. i. 4); the ungodly are “like the chaff which the wind drives away,” which signifies not their destruction, but their disposition, for their destruction is inferred from it (ver. 5), “therefore the ungodly shall not stand in judgment.” How contrary is this to the unchangeable God, who is alway the same, and would have us the same, in our religious promises and resolutions for good!

4. If God be immutable, it is sad news to those that are resolved in wickedness, or careless of returning to that duty he requires. Sinners must not expect that God will alter his will, make a breach upon his nature, and violate his own word to gratify their lusts. No, it is not reasonable God should dishonor himself to secure them, and cease to be God, that they may continue to be wicked, by changing his own nature, that they may be unchanged in their vanity. God is the same; goodness is as amiable in his sight, and sin as abominable in his eyes now, as it was at the beginning of the world. Being the same God, he is the same enemy to the wicked as the same friend to the righteous. He is the same in knowledge, and cannot forget sinful acts. He is the same in will, and cannot approve of unrighteous practices. Goodness cannot but be alway the object of his love, and wickedness cannot but be alway the object of his hatred: and as his aversion to sin is alway the same, so as he hath been in his judgments upon sinners, the same he will be still; for the same perfection of immutability belongs to his justice for the punishment of sin, as to his holiness for his disaffection to sin. Though the covenant of works was changeable by the crime of man violating it, yet it was unchangeable in regard of God’s justice vindicating it, which is inflexible in the punishment of the breaches of his law. The law had a preceptive part, and a minatory part: when man changed the observation of the precept, the righteous nature of God could not null the execution of the threatening; he could not, upon the account of this perfection, neglect his just word, and countenance the unrighteous transgression. Though there were no more rational creatures in being but Adam and Eve, yet God subjected them to that death he had assured them of: and from this immutability of his will, ariseth the necessity of the suffering of the Son of God for the relief of the apostate creature. His will in the second covenant is as unchangeable as that in the first, only repentance is settled as the condition of the second, which was not indulged in the first; and without repentance, the sinner must irrevocably perish, or God must change his nature: there must be a change in man; there can be none in God; his bow is bent, his arrows are ready, if the wicked do not turn (Ps. vii. 11). There is not an atheist, an hypocrite, a profane person, that ever was upon the earth, but God’s soul abhorred him as such, and the like he will abhor forever; while any therefore continue so, they may sooner expect the heavens should roll as they please, the sun stand still at their order, the stars change their course at their beck, than that God should change his nature, which is opposite to profaneness and vanity; “Who hath hardened himself against him, and hath prospered?” (Job ix. 4.)

Use 2. Of comfort. The immutability of a good God is a strong ground of consolation. Subjects wish a good prince to live forever, as being loth to change him, but care not how soon they are rid of an oppressor. This unchangeableness of God’s will shows him as ready to accept any that come to him as ever he was; so that we may with confidence make our address to him, since he cannot change his affections to goodness. The fear of change in a friend hinders a full reliance upon him; an assurance of stability encourages hope and confidence. This attribute is the strongest prop for faith in all our addresses; it is not a single perfection, but the glory of all those that belong to his nature; for he is unchangeable in his love (Jer. xxxi. 3), in his truth (Ps. cxvii. 2). The more solemn revelation of himself in this name, Jehovah, which signifies chiefly his eternity and immutability, was to support the Israelites’ faith in expectation of a deliverance from Egypt, that he had not retracted his purpose, and his promise made to Abraham for giving Canaan to his posterity (Exod. iii. 14–17). Herein is the basis and strength of all his promises; therefore, saith the Psalmist, “Those that know thy name, will put their trust in thee” (Ps. ix. 10): those that are spiritually acquainted with thy name, Jehovah, and have a true sense of it upon their hearts, will put their trust in thee. His goodness could not be distrusted, if his unchangeableness were well apprehended and considered. All distrust would fly before it, as darkness before the sun; it only gets advantage of us when we are not well grounded in his name; and if ever we trusted God, we have the same reason to trust him forever: (Isa. xxvi. 4) “Trust in the Lord forever, for in the Lord Jehovah is everlasting strength;” or, as it is in the Hebrew, “a Rock of Ages,” that is, perpetually unchangeable. We find the traces of God’s immutability in the creatures. He has, by his peremptory decree, set bounds to the sea: “Hitherto shalt thou come, but no further, and here shall thy proud waves be stayed” (Job xxxviii. 11). Do we fear the sea overflowing us in this island? No, because of his fixed decree. And is not his promise in his Word as unchangeable as his word concerning inanimate things, as good a ground to rest upon?

1. The covenant stands unchangeable. Mutable creatures break their leagues and covenants, and snap them asunder like Samson’s cords, when they are not accommodated to their interests. But an unchangeable God keeps his: “The mountains shall depart, and the hills be removed, but my kindness shall not depart from thee, nor shall the covenant of my peace be removed” (Isa. liv. 10). The heaven and earth shall sooner fall asunder, and the strongest and firmest parts of the creation crumble to dust, sooner than one iota of my covenant shall fail. It depends upon the unchangeableness of his will and the unchangeableness of his word, and, therefore, is called “the immutability of his counsel” (Heb. vi. 17). It is the fruit of the everlasting purpose of God; whence the apostle links purpose and grace together (2 Tim. i. 9). A covenant with a nation may be changeable, because it may not be built upon the eternal purpose of God, “to put his fear in the heart;” but with respect to the creature’s obedience. Thus God chose Jerusalem as the place wherein he would “dwell forever” (Ps. cxxxii. 14), yet he threatens to depart from them when they had broken covenant with him; “and the glory of the Lord went up from the midst of the city to the mountain on the east side” (Ezek. xi. 33). The covenant of grace doth not run, “I will be your God if you will be my people;” but “I will be their God, and they shall be my people” (Hos. ii. 19, &c.) “I will betroth thee to me forever; I will say, Thou art my people, and they shall say, Thou art my God.” His everlasting purpose is, to write his laws in the hearts of the elect. He puts a condition to his covenant of grace, the condition of faith, and he resolves to work that condition in the hearts of the elect; and, therefore, believers have two immutable pillars for their support, stronger than those erected by Solomon at the porch of the temple (1 Kings vii. 21), called Jakin and Boaz, to note the firmness of that building dedicated to God; these are election, or the standing, counsel of God, and the covenant of grace. He will not revoke the covenant, and blot the names of his elect out of the book of life.

2. Perseverance is ascertained. It consists not with the majesty of God to call a person effectually to himself to‑day, to make him fit for his eternal love, to give him faith, and take away that faith to‑morrow. His effectual call is the fruit of his eternal election, and that counsel hath no other foundation but his constant and unchangeable will; a foundation that stands sure, and, therefore, called the foundation of God, and not of the creature; “the foundation of God stands sure, the Lord knows who are his” (2 Tim. ii. 19). It is not founded upon our own natural strength; it may be then subject to change, as all the products of nature are. The fallen angels had created grace in their innocency, but lost it by their fall. Were this the foundation of the creature, it might soon be shaken; since man, after his revolt, can ascribe nothing constant to himself, but his own inconstancy. But the foundation is not in the infirmity of nature, but the strength of grace, and of the grace of God, who is immutable, who wants not virtue to be able, nor kindness to be willing, to preserve his own foundation.631 To what purpose doth our Saviour tell his disciples their names “were written in heaven” (Luke x. 20), but to mark the infallible certainty of their salvation by an opposition to those things which perish, and have their “names written in the earth” (Jer. xvii. 23); or upon the sand, where they may be defaced? And why should Christ order his disciples to rejoice that their names were written in heaven, if God were changeable to blot them out again? or why should the apostle assure us, that though God had rejected the greatest part of the Jews, he had not, therefore, rejected his people elected according to his purpose and immutable counsel; because there are none of the elect of God but will come to salvation? For, saith he, the “election hath obtained it” (Rom. xi. 7); that is, all those that are of the election have obtained it, and the others are hardened. Where the seal of sanctification is stamped, it is a testimony of God’s election, and that foundation shall stand sure: “The foundation of the Lord stands sure, having this seal, the Lord knows who are his;” that is the foundation, the “naming the name of Christ,” or believing in Christ, and “departing from iniquity,” is the seal.632 As it is impossible when God calls those things that are not, but that they should spring up into being and appear before him; so it is impossible but that the seed of God, by his eternal purpose, should be brought to a spiritual life, and that calling cannot be retracted; for that “gift and calling is without repentance” (Rom. xi. 29). And when repentance is removed from God in regard of some works, the immutability of those works is declared; and the reason of that immutability is their pure dependence on the eternal favor and unchangeable grace of God “purposed in himself” (Eph. i. 9, 11), and not upon the mutability of the creature. Hence their happiness is not as patents among men, quam diu bene se gesserint, so long as they behave themselves well; but they have a promise that they shall behave themselves so as never wholly to depart from God (Jer. xxxii. 40): “I will make an everlasting covenant with them, that I will not turn away from them to do them good, but I will put my fear in their hearts, that they shall not depart from me.” God will not turn from them, to do them good, and promiseth that they shall not turn from him forever, or forsake him. And the bottom of it is the everlasting covenant, and, therefore, believing and sealing for security are linked together (Eph. i. 13). And when God doth inwardly teach us his law, he puts in a will not to depart from it: (Ps. cxix. 102) “I have not departed from thy judgments;” what is the reason? “For thou hast taught me.”
