A systematic theological treatment examines salvation and the church, beginning with the reconciliation of humanity to God and the Holy Spirit's role in applying Christ's redemption. It surveys election and calling, then analyzes union with Christ, regeneration (its necessity, cause, instrumentality, and character), conversion through repentance and faith, and justification including its definition, evidences, elements, and relations to law, holiness, union with Christ, and faith. It proceeds to sanctification and perseverance, and concludes with ecclesiology: definitions, organization, government—arguing for congregational polity—offices and pastoral functions, and refutations of alternative views.
