What does it mean that Jesus was victorious over sin?

The victory of Jesus over sin is multidimensional, encompassing His complete obedience to the Father's will and the successful accomplishment of our redemption. By His atoning sacrifice, Jesus restored all that humanity lost in Adam—righteousness, life, and our rightful inheritance. As proclaimed in Romans 8:37, we are more than conquerors through Him who loved us. This victorious stance not only affirms that the power and penalty of sin have been definitively dealt with but also assures believers of their eternal victory and union with Christ, granting them hope and assurance in their salvation.
