Christ's victory on the cross has freed believers from sin's dominion, transforming our identity and giving us a new relationship with God. Through His death and resurrection, Jesus conquered sin and death completely, fulfilling God's promise from Genesis to Revelation. While we still experience the voice of our old self and struggle with sinful patterns, sin no longer has legal authority over us. By deliberately praying, renewing our thinking through Scripture, and presenting our bodies as instruments for righteousness, we can live out Christ's victory in our daily lives.
