How do we know Jesus' sacrifice frees us from sin?

The assurance that Jesus' sacrifice frees us from the bondage of sin is deeply rooted in the doctrine of justification through faith. Romans 6:10 states that Christ died once for sin, and this singular act secured salvation for His people, as affirmed in Hebrews 10:10, which declares that Christ's offering sanctifies those He calls. The believer must acknowledge that this sacrificial act was sufficient to pay the penalty of sin for all who believe, and it is through faith in Jesus' work that we are released from the reign of sin in our lives. The truth of our liberation is not based on our performance but solely on Christ's finished work.
