How do we know that Christ has destroyed sin?

Romans 6:6 proclaims that 'our old man is crucified with Him, that the body of sin might be destroyed.' This proclaims that through Christ's death, our sins have been judged, executed, and buried, thus freeing us from their power and condemnation. The sacrificial death of Christ not only serves as the perfect atonement for sin but also signifies the end of the dominion of sin over those who believe. As a result, believers are viewed as justified before God, with no accusations able to stand against them. Therefore, the assurance of Christ's victory over sin is foundational to the believer's identity in Him.
