The concept of coexistence with sin is a significant theme in Christian theology, reflecting the tension between the believer's new life in Christ and the persistent presence of sin in the world and within oneself. This entry explores the biblical understanding of this coexistence, the believer's struggle against sin, and the call to holiness.

Biblical Understanding

The Bible acknowledges the reality of sin in the world and its pervasive influence on humanity. In Romans 3:23, the Apostle Paul states, "for all have sinned and fall short of the glory of God." This universal condition underscores the need for redemption and the transformative power of the Gospel. Despite being justified by faith, believers continue to live in a fallen world where sin is ever-present.

The Believer's Struggle

The struggle against sin is a recurring theme in the New Testament. Paul vividly describes this internal conflict in Romans 7:15-25, where he writes, "For I do not understand my own actions. For I do not do what I want, but I do the very thing I hate." This passage highlights the tension between the desire to live righteously and the reality of sinful inclinations.

Galatians 5:17 further elaborates on this struggle: "For the flesh craves what is contrary to the Spirit, and the Spirit what is contrary to the flesh. They are opposed to each other, so that you do not do what you want." The believer is called to walk by the Spirit, resisting the desires of the flesh and striving for holiness.

The Call to Holiness

Despite the coexistence with sin, Scripture calls believers to pursue holiness and sanctification. In 1 Peter 1:15-16, it is written, "But just as He who called you is holy, so be holy in all you do, for it is written: 'Be holy, because I am holy.'" This call to holiness is not merely an ideal but a command that reflects the believer's new identity in Christ.

The process of sanctification involves a continual turning away from sin and a turning toward God. Romans 6:12-14 exhorts believers, "Therefore do not let sin reign in your mortal body so that you obey its desires. Do not present the parts of your body to sin as instruments of wickedness, but present yourselves to God as those who have been brought from death to life, and present the parts of your body to Him as instruments of righteousness."

Victory through Christ

While the struggle with sin is real, the Bible assures believers of victory through Jesus Christ. In 1 Corinthians 15:57, Paul declares, "But thanks be to God, who gives us the victory through our Lord Jesus Christ." This victory is not achieved by human effort but through the power of the Holy Spirit working within the believer.

Romans 8:1-2 offers further assurance: "Therefore, there is now no condemnation for those who are in Christ Jesus. For in Christ Jesus the law of the Spirit of life set you free from the law of sin and death." This freedom empowers believers to live in a manner that reflects their new life in Christ, even as they navigate the challenges of a world marred by sin.

Practical Implications

The coexistence with sin necessitates vigilance and reliance on God's grace. Ephesians 6:11-13 instructs believers to "put on the full armor of God, so that you can make your stand against the devil’s schemes." This spiritual armor equips believers to withstand the temptations and trials that accompany life in a fallen world.

Moreover, the community of faith plays a crucial role in supporting believers in their struggle against sin. Hebrews 10:24-25 encourages mutual encouragement and accountability: "And let us consider how to spur one another on to love and good deeds. Let us not neglect meeting together, as some have made a habit, but let us encourage one another, and all the more as you see the Day approaching."

In summary, the coexistence with sin is a complex reality for believers, marked by an ongoing struggle and a call to holiness. Through the power of the Holy Spirit and the support of the Christian community, believers are equipped to live victoriously in Christ, even amidst the challenges of a sinful world.
