Galatians 2:20 expresses one of the most radical and decisive realities of the Christian life: “I am crucified with Christ: nevertheless I live; yet not I, but Christ lives in me.” Paul makes a clear distinction between his former self the carnal self, the fleshly “I” that acted according to worldly desires, impulses, and influences and his present life in Christ. This old self, governed by the world and its lusts, has been crucified. It no longer governs, no longer directs, no longer acts. In its place, Christ lives in him.
This statement is not symbolic or poetic. It is a real spiritual condition. If Christ lives in a man, then the life manifested through that man must reflect Christ Himself. And in Christ, there is no sin, no impurity, no compromise, no darkness. Christ does not sin. There is no trace of sin in Him. Therefore, a life truly governed by Christ is a life without sin, because the source of that life is holy.
Paul confirms this reality elsewhere when he says, “the world is crucified unto me, and I unto the world.” This means that the world no longer has influence, attraction, or authority over him, just as a crucified man no longer responds to stimuli. The believer who is truly crucified with Christ no longer lives according to worldly standards, values, or desires. He lives according to Christ, and Christ’s life is one of perfect holiness.
The apostle John expresses the same truth when he says, “As He is, so are we in this world.” This statement leaves no room for a sinful Christian identity. If Christ is holy, and if we are as He is in this world, then our life must be marked by holiness, purity, and separation from sin. This is not arrogance; it is fidelity to the reality of union with Christ.
John further reinforces this in 1 John 3:3: “Everyone who has this hope in Him purifies himself, just as He is pure.” The measure of our purification is Christ Himself. Not a reduced standard. Not a human approximation. As He is pure, so must we be pure. This purification is not partial or occasional; it is constant, deliberate, and complete. A man who truly hopes in Christ cannot tolerate sin, because sin contradicts the very life of Christ within him.
Therefore, to say “Christ lives in me” while continuing to sin is a contradiction. If Christ lives in a man, then His holiness governs that man’s thoughts, imaginations, words, attitudes, actions, and entire conduct. To be worthy of this calling means to live in a way that reflects the One who lives within us without sin, without compromise, without returning to the old self.
This is the dignity of the Christian vocation: not merely to be forgiven, but to be transformed; not merely to believe, but to live Christ’s life; not merely to confess His name, but to manifest His holiness. Christ living in us means a life governed by His purity, His righteousness, and His complete freedom from sin here and now, in this world.
