Meaning: The quote "Do you mortify? Do you make it your daily work? Be always at it whilst you live; cease not a day from this work; be killing sin or it will be killing you," by John Owen, a prominent English theologian, captures the essence of the Christian concept of mortification. In religious terms, mortification refers to the practice of self-denial and discipline to overcome sinful tendencies and purify the soul. John Owen's quote emphasizes the continuous and diligent effort required to resist and overcome sin in one's life.

In the context of Christian theology, the term "mortify" is derived from the Latin word "mortificare," which means to put to death or subdue. This concept is deeply rooted in the Christian doctrine of sanctification, the process by which believers are progressively transformed into the likeness of Christ. According to this doctrine, the Christian life involves a constant struggle against the forces of sin, and mortification is seen as a necessary discipline to counteract the corrupt desires of the human heart.

John Owen's quote underscores the urgency and persistence required in the practice of mortification. The phrase "Do you mortify? Do you make it your daily work?" highlights the need for a deliberate and consistent effort to confront and overcome sin. It suggests that mortification should not be a sporadic or occasional activity but rather a daily and ongoing commitment. This aligns with the biblical exhortation to "put to death the deeds of the body" (Romans 8:13) and to "work out your own salvation with fear and trembling" (Philippians 2:12).

The admonition to "be always at it whilst you live; cease not a day from this work" emphasizes the lifelong nature of the struggle against sin. According to Owen, the pursuit of holiness and the battle against sin are not temporary endeavors but enduring aspects of the Christian journey. This echoes the biblical call to "fight the good fight of the faith" (1 Timothy 6:12) and to "run with endurance the race that is set before us" (Hebrews 12:1).

The final warning, "be killing sin or it will be killing you," encapsulates the high stakes involved in the practice of mortification. Owen's stark imagery vividly conveys the life-or-death nature of the spiritual warfare against sin. The implication is that failure to actively engage in the process of mortification leaves one vulnerable to the destructive and enslaving power of sin. This sentiment echoes the biblical caution that "the wages of sin is death" (Romans 6:23) and underscores the existential significance of the believer's ongoing struggle for holiness.

In summary, John Owen's quote encapsulates the arduous and unrelenting nature of the Christian's pursuit of holiness through the practice of mortification. It underscores the daily, lifelong, and high-stakes commitment required to resist and subdue the power of sin. For believers, this quote serves as a potent reminder of the imperative to actively engage in the ongoing battle against sin and to pursue a life marked by spiritual discipline and moral integrity.
