How does Christ's successful work impact believers today?

Believers today are empowered by understanding the fullness of Christ's accomplished work, which includes their justification and sanctification. In His successful mission, noted in Psalm 21:4-5, Christ secured eternal life for His people, meaning that their standing before God is complete and unshakeable. They are not left to rely on their efforts but can rest in the perfect atonement and advocacy of Christ. This impacts their identity as children of God, giving them confidence in prayer, in their union with Christ, and in the promise of future glory. Therefore, believers can live in peace, knowing that all their needs and sins have been addressed through His work.
