Why is it important to understand Christ's victory over sin?

The sermon emphasizes that Christ came not just to fight but to win the victory over every enemy, including sin and death. This victory is not future but already accomplished through His redemptive work. As stated in 1 Corinthians 15:54, 'Death is swallowed up in victory,' showing that for believers, true death has no power. The assurance of Christ’s triumph provides believers with tremendous peace and confidence, knowing that they cannot die spiritually because He has already secured their eternal life. His victory confirms the promise of righteousness given to every believer, anchoring their hope in the Gospel.
