We know we are dead to sin because of our union with Christ, who was crucified and raised for our justification (Romans 6:6-8).
The concept of being dead to sin hinges on the believer's identification with Christ's death and resurrection. Romans 6 explains that when Christ died, believers symbolically died with Him, breaking the power of sin over their lives. This union means that we are no longer slaves to sin and that the punishment for our sins has already been absorbed by Christ. Thus, Paul encourages believers to reckon themselves as dead to sin but alive to God. This assurance comes not from our deeds, but from faith in Christ’s completed work, affirming the truth that our justification and sanctification are found solely in Him.
