How do we know Christ's work of redemption is sufficient?

The sufficiency of Christ's work of redemption is affirmed through His sacrificial death and resurrection. He declared, 'It is finished' (John 19:30), signifying that all requirements of God's justice were fulfilled. Hebrews 10:12 tells us that Christ, after offering one sacrifice for sins, sat down at the right hand of God, indicating that His atonement was complete and accepted. Moreover, 2 Corinthians 5:1 assures believers that they await an eternal dwelling with God, further confirming the victory achieved by Christ over sin and death and underscoring that nothing can be added to this redemptive work.
