How do we know that Christ's sacrifice breaks the power of sin?

The power of sin is broken through the redemptive work of Jesus Christ. As stated in the sermon, He fulfilled the law through His perfect obedience and took upon Himself our sins as our substitute, thus satisfying God's justice. Romans 6 elaborates on this transformative work, explaining that believers are no longer under law but under grace, and that sin shall not have dominion over us. This newfound freedom is a sure result of Jesus' atoning sacrifice, which not only provides forgiveness of sins but also enables us to live righteously as His followers. The truth of this doctrine assures believers that through faith in Christ, they are empowered to resist sin and live according to God's will.
