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

The completion of Christ's work of redemption is powerfully affirmed through His resurrection and the authority of Scripture. In Hebrews 4:3, we learn that the works of God were finished from the foundation of the world, culminating in the perfect sacrifice of Jesus at Calvary. When He declared 'It is finished,' as mentioned in John 19:30, He signified that the debt for sin was fully paid. This act of atonement not only covered our sins but also opened the door to the righteousness that God requires of us.

Furthermore, the resurrection of Jesus serves as the divine endorsement of His finished work. As Romans 4:25 states, He was delivered up for our offenses and raised for our justification. His resurrection not only validates His claims but also assures believers that they have been justified before God. The scripture testifies repeatedly to this completed work, reinforcing our faith in Christ's sufficiency and the reality of our salvation.
