The work outlines a practical theology of absolute surrender to divine providence, establishing three core principles: God's eternal knowledge and permissive will, the alignment of divine permission with his ultimate ends, and the inseparability of human sanctification from divine glory. It distinguishes events beyond human control from those caused by others, prescribing complete, loving acceptance for the former and a measured response for the latter that rejects resentment, seeks spiritual profit, and cooperates with duty. Emphasis falls on active responsibility followed by confident abandonment, the sanctifying value of real and imagined trials, and caution against misreadings that justify passivity.
