In “The Mortification of Sin,” John Owen delves into the depths of human struggle against sin, offering profound insights into the process of sanctification. Owen’s words resonate with a wisdom that is both timeless and deeply rooted in the Reformed theology. He masterfully captures the essence of our constant battle with sin and presents a practical roadmap for believers seeking to mortify its influence in their lives.

Owen’s assertion that “Be killing sin or it will be killing you” (p. 27) serves as the clarion call for readers to understand the urgency of this battle. His exploration of the deceitfulness of the human heart and its entanglement with sin is strikingly accurate, as he asserts, “Sin aims always at the utmost; every time it rises up to tempt or entice, might it have its own course, it would go out to the utmost sin of that kind” (p. 51).

Throughout the book, Owen meticulously dissects the process of mortification, highlighting the role of the Holy Spirit in empowering believers to overcome sin’s grip. His discussion of the relationship between our affections and actions, as seen in the statement “Right thoughts of God, and of Christ, and a due valuation of the love of God in Christ, will sanctify a man throughout in all his actions” (p. 74), resonates with the heart of Reformed theology.

Owen’s practical advice on applying biblical principles for mortification is equally compelling. His words on the necessity of consistent self-examination, encapsulated by the assertion “He that doth not every day endeavour to obtain more of this hatred of sin, doth not make it his business to mortify sin” (p. 110), provide guidance for believers seeking to make meaningful progress in their sanctification journey.

As a Reformed pastor, I found Owen’s insights to be deeply aligned with the theological framework that underpins our faith. His exploration of the complexities of indwelling sin and the transformative power of God’s grace speaks directly to the struggles faced by many in our congregations. “The Mortification of Sin” is undoubtedly a profound resource that has the potential to revolutionize our understanding of sanctification and equip us to guide our flock with renewed conviction.
