How Do I Kill Remaining Sin?

Order this book

Are you truly dying to sin each day? If not, this book declares, then you have not yet begun to live fully as a disciple of Christ. This bold statement introduces a powerful work that addresses one of the most crucial aspects of the Christian life: the ongoing battle against indwelling sin.

When God saves a person through the death and resurrection of Jesus Christ, He not only grants forgiveness, but also begins a transformative process within them—a call to die daily to sin and to live in new obedience united with Christ. Although the new birth brings deep changes to the believer’s heart, no Christian is exempt from struggling against remnants of sin. The presence of this sinful inclination—known as “remaining sin”—requires constant vigilance, sincere repentance, and complete dependence on the Holy Spirit.

In this short but profound book, Pastor Geoffrey Thomas, with his clear, biblical, and pastoral style, offers practical and deeply spiritual guidance on how believers can effectively fight sin in their lives. Grounded in Scripture, he explains how we can, by the grace of Christ, overcome sin and grow in holiness, reflecting more and more the image of Jesus.

This book does not remain at the level of abstract concepts, but rather seeks to:

• Awaken a biblical awareness of the danger of sin.
• Encourage the faithful use of the means of grace: prayer, Scripture, and fellowship.
• Help readers cultivate a life of spiritual mortification.
• Promote a Christ-centered vision of personal sanctification.

As part of a series designed to strengthen the Christian life from its foundations with biblical depth, this book aims to instruct the mind, move the heart, and transform the life through the work of the Holy Spirit.

Ultimately, all of this serves a greater purpose: that Christians may “adorn the doctrine of God our Savior in every way” (Titus 2:10), showing the world the beauty of Christ through a life of piety and obedience.
