What does the Bible say about Jesus accomplishing salvation?

In Luke 18:31, Jesus declares, 'Behold, we go up to Jerusalem, and all things that are written by the prophets concerning the Son of Man shall be accomplished.' This signifies that His work on the cross was not an attempt but a definitive act of salvation. The term 'accomplished' speaks to the certainty and completeness of His redemptive work, ensuring that every prophecy concerning Him would be fulfilled. He was sent by God as the Lamb slain before the foundation of the world, indicating that His mission was divinely ordained and certain to succeed.
