What does the Bible say about the significance of Jesus' statement 'It is finished'?

The phrase 'It is finished' signifies the culmination of Jesus' mission to save His people from their sins. In John 19:30, Christ's declaration comes at the conclusion of His suffering on the cross, indicating that all the demands of the law have been fulfilled and that the atonement for sins has been accomplished. This perfect sacrifice means that there is nothing left for believers to do but to trust in His finished work. This completion reflects Jesus' role as the Lamb of God, who was slain from the foundation of the world, fulfilling God's redemptive plan for His chosen people.

Moreover, this declaration assures believers of their salvation, as it emphasizes that salvation is not based on their merit or efforts but solely on what Christ has achieved. The work of redemption is complete, and through belief in Him, they can rest in the certainty of their salvation. Thus, ‘It is finished’ serves as both a triumph over sin and a clarion call for all to put their hope in Christ alone.
