Why is the cry 'It is finished' significant?

'It is finished,' the final proclamation of Jesus on the cross, is a powerful affirmation of the completion of His redemptive work. This cry indicates that He has successfully accomplished all that was necessary for the salvation of His people. It encompasses the fulfillment of the Old Testament prophecies and the legal payment for sin, affirming that the burden of sin has been fully paid. This declaration assures believers that they are justified in God's sight through faith in Christ's completed work. As the one perfect sacrifice, Jesus provides lasting atonement, signifying that nothing more is required for salvation. This underscores the doctrine of justification by faith alone, vital for Christians cherishing the grace of God.
