Question

“How to defeat flesh? Like the desires of the flesh.”

Answer

The Christian life carries within it a real tension: a person longs for God, yet at the same time experiences within himself a tendency to move outside of God’s will. Holy Scripture describes this conflict as the struggle between the Spirit and the flesh. Yet this is not merely a battle with individual temptations. It is something deeper: a conflict between the life that comes from God and the human tendency to turn inward upon oneself.

So the question is not only, How do we stop sinning? Rather, it is this: How do we enter into such a life with God that the desires of the flesh lose their attraction? The Christian answer is radical: this is not merely about moral improvement, but about the mystery that Christ truly lives in us. The Apostle Paul says, “It is no longer I who live, but Christ who lives in me” (Galatians 2:20). This is the heart of holiness.

What Are the Desires of the Flesh?

When Scripture speaks about the flesh, it does not mean merely bodily existence. It speaks of the person living apart from God, ruled by self, self-will, and disobedience. The desires of the flesh, then, are the inclinations of fallen human nature to resist God’s will and to seek life apart from Him.

This is why the desires of the flesh become a source not only of sin, but also of inner misery and disintegration. The human person was created for God. When one turns away from Him, one does not merely violate a commandment, but also goes against the truth of one’s own being. The desires of the flesh may take the form of impurity, pride, anger, envy, selfishness, or spiritual laziness, yet their root is the same: the person does not want to receive God’s will as the place of life.

Called to Holiness Already Now

God does not call the Christian merely to avoid sin. He calls the Christian to holiness. “Be holy, for I am holy.” Holiness is not an unreachable ideal or the privilege of a few chosen souls. It is the calling of every believer.

This must be said clearly: true communion with God and real growth in holiness are possible already in this life. Not yet in the perfect fullness of heaven, but truly and really even now. And this is not only about becoming “like” Christ. It is something deeper: Christ does not merely stand before us as an example, but desires to live in us. Holiness, then, is not mere imitation, but participation in the life of Christ.

Walk by the Spirit

Saint Paul writes: “Walk by the Spirit, and you will not gratify the desires of the flesh” (Galatians 5:16). This is one of the central keys to the spiritual life. Victory over the flesh does not come first of all from an obsession with one’s own sin, but from life in the Holy Spirit.

Even mortification of the flesh must be understood properly. It certainly includes a real struggle against sin, yet its deeper aim is not mere repression, but the transformation of desire by the Holy Spirit. Through the Spirit, the heart is gradually changed, so that the desires of the flesh lose much of their power and attractiveness, even though the struggle itself may remain.

On the other hand, what becomes increasingly beautiful to the soul is the fruit of the Spirit: love, peace, purity, obedience, truth, and joy in God. This is a deeper victory than merely refraining outwardly from sin.

Renewal of the Mind and Mortification of the Flesh

Paul says: “Do not be conformed to this world, but be transformed by the renewal of your mind” (Romans 12:2). Sin has power partly because it deceives. It presents self-will as freedom and disobedience as the path to life. But in truth, it leads to emptiness.

For this reason, the renewal of the mind is necessary through prayer, the Word of God, silence, repentance, and sacramental life. When a person’s vision changes, his desires begin to change as well.

This is connected to Paul’s words: “If by the Spirit you put to death the deeds of the body, you will live” (Romans 8:13). The important words are these: by the Spirit. Not merely by self-control, but by the power of the Holy Spirit. The Christian does not fight alone. Christ lives in him, and God is at work within him.

Fleeing Temptation and the Beauty of the Spirit’s Fruit

Scripture is also very practical. “Flee from sexual immorality” (1 Corinthians 6:18). Some temptations are not overcome by prolonged dialogue, but by wise flight. The one who seeks holiness does not proudly rely on himself, but guards his heart and avoids what he knows will weaken him.

Yet the goal is not merely to “manage not to do evil.” The goal is that the fruit of the Spirit would become sweeter to the soul than sin. That purity would not be experienced only as a prohibition, but as beauty. That obedience would not be a burden, but a place of peace. A person is not set free from sin merely by the command, “You must not.” He must encounter a greater good.

The Gradual Nature of This Transformation

This transformation is ordinarily gradual. Even where Christ truly dwells in a person, the struggle against the flesh often remains real and painful. Growth in holiness does not mean the absence of temptation, nor does every fall prove that grace is absent. Rather, the Christian life is marked by continual repentance, deeper dependence on mercy, and a growing conformity to Christ through perseverance.

For this reason, no one should imagine that spiritual maturity means effortless victory in every moment. In many cases, holiness is seen not in the disappearance of conflict, but in steadfastness, humility, repentance, and continued faithfulness in the midst of conflict.

Christ in Us as the True Victory

At the deepest level, Christian holiness consists in this: Christ Himself dwells in the human person. So when we speak about victory over the flesh, we are not speaking merely of an ethical achievement. We are speaking of the old man decreasing so that Christ may have room. That Christ may think in us, love in us, and obey the Father in us.

This is also the meaning of the struggle against the desires of the flesh: not merely resistance to sin, but openness to a new life.

Conclusion

How, then, do we overcome the desires of the flesh? Not first of all by our own strength, but by opening ourselves to the Holy Spirit, who brings about the life of Christ within us. The desire of the flesh is the inclination to go outside of God’s will. Freedom, therefore, is found in returning to God’s will, because His will is the place of life.

When Christ lives in a person, sin loses its taste. And the soul begins to know the sweetness of the things of God. This is the true mortification of the flesh: not merely suppressing evil inclinations, but such a transformation of the heart that the old becomes bitter and the new becomes sweet.

And where Christ lives, true freedom begins.
