Mortification of Sin

John Owen's "The Mortification of Sin" emerged from his pastoral concern for Christians struggling with persistent sin patterns in their spiritual lives. Originally delivered as sermons at Oxford in the 1650s during Owen's tenure as dean of Christ Church, the work addresses believers who found themselves caught between their new identity in Christ and the continuing reality of sinful desires. Owen wrote for those who understood justification by faith but remained confused about how sanctification actually works in daily experience.

Owen builds his treatise around Romans 8:13, arguing that the Christian's lifelong work of "mortifying" sin requires both divine grace and human effort working in concert. He insists that only regenerate believers can truly mortify sin, since the unregenerate lack the Holy Spirit's power necessary for this work. The mortification process involves recognizing specific sins, understanding their root causes in the heart, and applying gospel remedies through prayer, meditation on Christ's cross, and deliberate cultivation of opposing virtues. Owen emphasizes that this is not mere behavioral modification but a deep spiritual warfare that requires understanding both the deceitfulness of sin and the sufficiency of Christ's atonement. He warns against both legalistic self-effort and antinomian passivity, charting a middle course that takes seriously both human responsibility and divine enablement.

Owen's psychological insight into how sin operates in the human heart has kept this work influential across denominational lines for over three centuries. His clinical precision in describing sin's tactics and his pastoral wisdom in applying gospel remedies continue to serve pastors, counselors, and serious Christians wrestling with habitual sins. This work should be read by mature believers ready for rigorous self-examination and those in pastoral ministry who counsel others through sin struggles. It is not suited for new Christians who need encouragement in basic gospel truths rather than advanced instruction in spiritual warfare.
