Nailed to the Cross: What It Means to Crucify the Flesh and Walk by the Spirit

A Life of the Spirit Begins with the Death of the Flesh

The Christian life is not merely a call to improvement—it is a call to death and resurrection. To live by the Spirit, the flesh must be crucified. This is not figurative language. It is the vivid reality of what it means to follow Christ. In Galatians 5:24, Paul makes this declaration:

Galatians 5:24
“And those who are Christ’s have crucified the flesh with its passions and desires.”

This verse draws a line in the sand. To belong to Christ is to declare war against the sinful nature. To walk in step with the Holy Spirit, the old self—its cravings, its instincts, its patterns—must be nailed to the cross and left there. Crucifying the flesh is not about behavior modification; it is about spiritual execution. It is a once-for-all act of decisive surrender and a daily commitment to live from a new source: the Spirit of God.

What Is the Flesh—and Why Must It Be Crucified?

The flesh in Scripture refers not to the physical body, but to the fallen nature inherited from Adam—a nature that is bent toward sin, self-rule, and rebellion against God. It manifests in selfishness, impurity, envy, rage, pride, and a host of other destructive behaviors. Paul earlier described these in Galatians 5:19–21, calling them the “works of the flesh.”

The flesh cannot be rehabilitated. It cannot be managed or disciplined into submission. It must be crucified. Jesus Himself taught this when He said:

Luke 9:23
“If anyone desires to come after Me, let him deny himself, and take up his cross daily, and follow Me.”

Crucifixion was a death sentence. To take up the cross is to die to self. To crucify the flesh is to decisively reject the rule of sin in our lives—not just in theory, but in practice. It means saying no to the impulses that once controlled us, and yes to the Spirit who now empowers us.

Crucifying the Flesh Is a Mark of Belonging to Christ

Paul makes it clear that this act of crucifying the flesh is not reserved for elite Christians or spiritually mature leaders. It is the normal mark of all who belong to Jesus:

Galatians 5:24
“And those who are Christ’s have crucified the flesh with its passions and desires.”

This is identity language. Those who are Christ’s have not simply made a decision—they have undergone a death. They have aligned themselves with the cross, where their old nature was put to death with Christ. This crucifixion is both positional and practical:

• Positionally, the moment we are united with Christ through faith, we are counted as crucified with Him. Our old self is legally dead in God’s eyes (see Romans 6:6).

• Practically, we choose daily to live out that crucifixion—to deny the flesh its demands and live instead by the Spirit.

This is what distinguishes true disciples from religious pretenders. The true believer has not just invited Jesus into their life—they have surrendered their life to Jesus.

Crucifying the Flesh Is Both Past Tense and Present Action

When Paul says we have crucified the flesh, he uses the past tense. This reflects the decisive break with sin that occurs at salvation. Yet elsewhere, Paul speaks of a daily dying to self:

1 Corinthians 15:31
“I affirm, by the boasting in you which I have in Christ Jesus our Lord, I die daily.”

Though the power of the flesh was broken at the cross, its influence still lingers. The flesh is a dethroned tyrant that still tries to rule. Crucifying it is not a one-time emotional moment—it is a daily spiritual discipline. It is the conscious choice to say:

• I will not feed that lustful thought.

• I will not entertain that prideful motive.

• I will not justify that bitter feeling.

• I will not follow that selfish impulse.

Instead, I will walk in the Spirit, and trust His power to produce in me what I cannot produce on my own.

Walking by the Spirit Is the Only Way to Stay Free

Immediately after this declaration in verse 24, Paul gives this command in Galatians 5:25:

Galatians 5:25
“If we live in the Spirit, let us also walk in the Spirit.”

Crucifying the flesh is not just about what we put off—it’s about what we put on. We don’t simply deny ourselves; we fill ourselves with the presence and power of the Holy Spirit. We walk with Him, listen to Him, follow Him.

To walk in the Spirit is to:

• Let Him guide your thoughts and attitudes.

• Let Him check your responses and reactions.

• Let Him convict you of sin and lead you to repentance.

• Let Him produce in you the Fruit of the Spirit—love, joy, peace, patience, and more.

When we walk in the Spirit, the flesh loses its grip. The temptations may still come, but the power to resist them grows. The Spirit empowers us to live in freedom, not bondage—to live in victory, not defeat.

The Cross Is Not Just Our Entry Point—It Is Our Lifestyle

Too many believers treat the cross as something they passed on the way to salvation. But the cross is not just the gate into the Christian life—it is the road itself. We never graduate from crucifying the flesh. The Spirit will always be leading us deeper into surrender and higher into holiness.

Paul’s personal testimony echoes this truth in Galatians 2:20:

Galatians 2:20
“I have been crucified with Christ; it is no longer I who live, but Christ lives in me;
and the life which I now live in the flesh I live by faith in the Son of God,
who loved me and gave Himself for me.”

This is the Spirit-led life. A life where the old has died and the new has come. A life of continual crucifixion and continual resurrection. A life where Jesus is not just Savior—but King.

Conclusion: Embrace the Cross, Experience the Power

Galatians 5:24 calls us to a defining reality:
“And those who are Christ’s have crucified the flesh with its passions and desires.”

To walk in the Spirit, the flesh must be nailed down. To live in freedom, sin must die. This is not a call to perfection—it is a call to surrender. The Spirit is not asking for your best effort; He is asking for your whole heart.

Let the cross be more than a symbol—let it be your lifestyle. Crucify the flesh, daily and decisively. Walk in the Spirit, joyfully and continually. And you will discover a life that is not only pleasing to God, but rich with power, purpose, and the character of Christ.

For in dying to self, you truly begin to live.
