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

The statement 'It is finished,' made by Jesus on the cross, carries profound theological significance in the context of salvation. It indicates that the legal demands of the law, which none can fulfill, are accomplished through Christ's perfect obedience and sacrificial death. In Romans 10:4, it is affirmed that Christ is the end of the law for righteousness to everyone who believes. This completion means that there is nothing more required for the justification of God's elect; it is all accomplished in Christ's atoning work. In essence, this declaration reassures believers that the work necessary for their salvation is fully completed, allowing them to rest in His finished work rather than in their own efforts.
