Why is Christ's victory over sin important for Christians?

The importance of Christ's victory over sin lies deeply in the doctrine of justification. As highlighted in Romans 5:18-21, 'Therefore, as through one man’s offense judgment came to all men, resulting in condemnation, even so through one Man’s righteous act the free gift came to all men, resulting in justification of life.' This indicates that just as sin came into the world through Adam, redemption and righteousness are made possible through Christ. His victory over sin not only justifies us but also empowers us to live a life pleasing to God. It assures believers that death and sin do not have power over them, allowing us to live in the freedom of grace.
