Remaining Sin in the Believer #3

Romans 7:18, "For I know that nothing good lives in me, that is, in my sinful nature."
Romans 7:21, "So I find this law at work: When I want to do good, evil is right there with me."
Romans 7:24, "What a wretched man I am! Who will rescue me from this body of death?"

One of the most painful realities in the Christian life is not merely that sin exists in the world, but that sin still clings to the believer. The regenerate heart longs to obey Jesus, delights in holiness, and hates wickedness—yet still discovers corruption lurking within. The mature believer eventually learns that sanctification is not a straight ascent into effortless holiness, but a fierce and lifelong war.

The Apostle Paul described this conflict with striking honesty:

"So this is the principle I have discovered: When I want to do good, evil is right there with me. For in my inner being I delight in God’s law. But I see another law at work in my body, warring against the law of my mind and holding me captive to the law of sin that dwells within me . . . What a wretched man I am! Who will rescue me from this body of death?" (Romans 7:21–24)

Paul was not describing an unbeliever who merely feels guilty. He was describing the normal experience of a justified saint who has been made alive by the Spirit but who still carries unglorified flesh. The believer possesses a new heart, but not yet a perfected one. Regeneration breaks sin’s dominion, but glorification alone will remove sin’s presence.

This truth guards the Christian from harmful errors:

First, this doctrine guards against despair. Many believers are crushed because they expected the Christian life to eliminate all internal struggle. They assume that recurring battles with pride, lust, anger, fear, selfishness, bitterness, or unbelief must mean they are lost. But Scripture teaches the opposite: the very presence of spiritual warfare is evidence of spiritual life. Dead hearts do not wage war against sin. Corpses feel no conflict.

Galatians describes this inward battle plainly:

"So I say, walk by the Spirit, and you will not gratify the desires of the flesh. 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." (Galatians 5:16–17)


The unbeliever may feel shame over consequences, but only the believer truly grieves sin because sin dishonors God. Remaining sin causes agony precisely because the heart has been changed. The sheep mourns what the goat celebrates.

Second, this doctrine guards against pride. The Christian who understands remaining sin, stops boasting in personal strength. Every victory over temptation is the mercy of God. Every step of obedience is empowered by grace. The believer learns to distrust the flesh and cling to Jesus.

The doctrine of remaining sin also destroys perfectionism. Scripture nowhere teaches that believers attain sinless perfection in this life. The Apostle John wrote:

"If we say we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness." (1 John 1:8–9)

Notice that John does not direct believers toward denial, but confession. Christians do not mature beyond the need for repentance. Rather, true maturity deepens repentance. The closer one walks with Jesus, the more sensitive the conscience becomes to the ugliness of sin and the beauty of holiness.

Yet remaining sin must never become an excuse for complacency. The believer cannot say, "Since sin remains, holiness is impossible." Scripture commands mortification. Christians are called to crucify sinful desires, fight temptation, pursue obedience, and walk by the Spirit. The presence of warfare does not justify surrender.

There is also profound comfort in remembering that Christ’s love for His people is not grounded in their flawless performance. The believer stands justified by the righteousness of Jesus alone. God does not accept His people because they have conquered every sin perfectly, but because Jesus perfectly obeyed in their place and fully satisfied divine justice at the cross.

This means the believer fights from victory, not for victory. The Christian battles sin not to earn adoption, but because adoption has already been secured by Jesus.

One day this war will end. At glorification, remaining sin will finally be eradicated forever:
No more wandering thoughts in prayer.
No more cold affections.
No more secret pride.
No more impurity.
No more fear.
No more battle.
The saints will love God with undivided hearts in perfect holiness.

Until then, every Christian walks humbly through the tension of Romans 7, while clinging triumphantly to Romans 8. Though sin remains, it no longer reigns. Though the battle continues, Jesus has already secured the final victory.

Therefore, weary believer, do not make peace with sin—but do not despair because of the battle either. Run continually to Jesus. Confess quickly. Repent sincerely. Depend entirely upon the Spirit. And remember that the Savior who justified you will also sanctify you and, in the end, glorify you.

The struggle against remaining sin is not proof that God has abandoned His people. It is proof that He has begun a work within them that He will certainly complete.
