The Apostle Paul teaches that when Christ was crucified, our old nature, our sinful self that once served sin, was also crucified with Him….

This truth reaches far beyond symbolic meaning; it speaks of a spiritual reality in which the believer’s former life is put to death through union with Christ.
Before salvation, humanity lived under the dominion of sin, powerless to break free from its tyranny. Sin ruled through the flesh, shaping thoughts, desires, and actions, and every attempt at moral improvement ultimately failed because of this underlying nature. But the moment we are joined with Christ by faith, in the eyes of God, we are seen as having died with Him. The old man is not simply restrained or reformed,it is crucified, put to death, and replaced by a new creation through the indwelling Spirit.

Because He died and rose again, the same life that now reigns in Christ reigns in those who belong to Him. Death no longer has power over Jesus, and because we are united with Him, death no longer has power over us. This means the guilt, penalty, and authority of sin are broken.
We may still feel the pull of our earthly nature, and the remnants of the flesh still seek to assert control, but the believer now lives under the dominion of grace rather than sin. The struggle we face in daily life is not to defeat sin by our own strength, but to walk in what Christ has already accomplished. His death was substitutionary; He took our place so that we might take on His life.
To live “dead to sin” and “alive unto God” is therefore not about achieving moral perfection but resting in the finished work of the Cross. Our baptism into His death symbolizes the complete end of the old order of life, while the resurrection we share through faith points to a new and powerful life; one abundant and free as promised in John 10:10.
Our victory is not earned through effort but received through faith. The more we understand that the old man is crucified, the more we walk as those truly alive, not under condemnation but in the liberty of Christ. In Him, death has lost its dominion, sin has lost its throne, and grace now reigns in righteousness unto eternal life.
