What does it mean to say Christ's work on the cross was finished?

The phrase 'It is finished' (John 19:30) encapsulates the fulfillment of Christ's mission to provide redemption for His people. In His atoning death, Jesus accomplished what was required to satisfy divine justice on behalf of sinners. This completion is a celebration of His authority and the joy He received from executing the will of the Father. The victory achieved on the cross assures believers that their sins are fully atoned for, and God's wrath is satisfied through Christ’s sacrifice. Therefore, believers can have full confidence in their eternal standing before God, knowing that righteousness has been fully provided through Christ's finished work.
