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

The phrase 'It is finished' (John 19:30) encapsulates the completion of the work that God sent Jesus to do. Literally translated from the original Greek, it implies that all debts have been paid in full, suggesting His victory over sin and death. This declaration signifies the culmination of prophecies, the fulfillment of the law, and the assurance that salvation is accomplished for all who believe in Him. It reflects not only the end of His earthly sufferings but also the perfection of His redemptive work, leaving nothing more for humanity to do in order to secure their salvation.
