The Christian’s Battle with Sin
I'm a "New Creation?" Why, Then, Do I Continue to Struggle with Sin?
The Christian life is full of paradoxes. Many truths seem to pull in opposite directions, yet they meet perfectly in Christ. One of the most profound paradoxes is this: believers are new creations, yet they still struggle with sin.
This raises an important question, and one that I am asked often as a pastor, “How can I have been made new in Christ, but continue to wrestle with the very things they’ve been freed from?”
Scripture holds these truths together, and understanding them deepens both our assurance and our humility.
The Miracle of the New Creation
When Paul declares, “If anyone is in Christ, he is a new creation; the old has passed away; behold, the new has come” (2 Cor. 5:17), he’s not describing a mild moral adjustment but a radical transformation. In union with Christ, the believer receives a new heart, new desires, and a new direction. What was once spiritually dead is made alive by the power of the Holy Spirit. Regeneration is not about turning over a new leaf, it is about being given a new life.
This new identity means that the believer’s relationship to sin has fundamentally changed. Sin no longer reigns. The Christian is no longer under condemnation (Rom. 8:1) but under grace. The chains of guilt, shame, and judgment have been broken. We are now God’s children, indwelt by His Spirit, empowered to love righteousness and resist evil. The old self has been crucified with Him (Rom. 6:6).
Yet if this is true, why do Christians still sin? Why do we still struggle with temptation? Why do we still feel the weight of failure?
The Reality of the Remaining Sin
The answer lies in understanding that while the believer’s old self has been crucified, the presence of sin remains. Theologians often describe this as the tension between the “already” and the “not yet.” Already, believers are justified, reconciled, and spiritually alive; but not yet are they glorified, fully freed from sin’s influence.
The apostle Paul gives voice to this tension in Romans 7. He writes, “The good that I want to do, I do not do; but the evil I do not want is what I keep on doing.” Paul is not describing the life of an unbeliever but of a redeemed Christian painfully aware of the battle within. The Holy Spirit has made him sensitive to sin’s presence, and that very sensitivity is evidence of new life.
Before conversion, sin ruled unopposed. After conversion, sin remains but must now battles with the indwelling Spirit. The Christian life with sin is one of continual warfare against it. Galatians 5:17 captures this battle, “The desires of the flesh are against the Spirit, and the desires of the Spirit are against the flesh.” The Spirit gives believers the power to say “no” to sin and “yes” to righteousness, even as the struggle continues.
This battle is not a sign of failure; it is actually a mark of belonging. The spiritually dead do not fight sin, they love it. The spiritually alive grieve over it and resist it. The struggle itself is evidence that the new creation is real.
Sanctification, the process of being made holy, is not instant perfection but steady progress. By God’s grace, the Christian learns to put off the old self and put on the new (Eph. 4:22–24). This daily renewal involves repentance, dependence on the Spirit, and faith in Christ’s finished work. Though the fight often makes us weary, the outcome is certain: “He who began a good work in you will bring it to completion at the day of Jesus Christ” (Phil. 1:6).
Every failure drives us back to the gospel; every victory points us forward to Glory. The Christian’s perseverance does not rest on self-discipline but on God’s faithfulness. In Christ, the believer’s future is secure, even as the present remains a battleground.
The Final Victory
The day is coming when the struggle will cease. The “not yet” will give way to the “fully realized.” Sin will be silenced forever, and the believer’s renewal will be complete. Until that day, we walk in the tension. We rejoice in the reality of being made new, and we grieve over what sin remains in us. Even more, we look with confidence to the Savior who promises, “Behold, I am making all things new” (Rev. 21:5).
The Christian is both a new creation and a work in progress. The same grace that made us new, sustains us in the struggle, and will one day finish the story.
