The volume collects a memoir and a series of doctrinal, experimental, and practical treatises in which the author recounts his spiritual autobiography, including conversion and imprisonment, and expounds core Protestant themes: justification by grace, the interplay of law and grace, the believer’s fears and privileges, prayer, and Christ’s advocacy. Plainspoken exhortation alternates with scriptural argumentation and illustrative anecdote, offering pastoral counsel for readers seeking assurance, moral examination, and guidance for practical holiness.
