What does the Bible say about Jesus' necessity to suffer and die?

In Matthew 16:21, Jesus clearly states to His disciples that He must go to Jerusalem, suffer many things, and be killed. This necessity is not arbitrary but rooted in divine necessity and the will of the Father. It reflects the fulfillment of Old Testament prophecies, particularly Isaiah 53, which describes the Messiah as a suffering servant. His death was not a defeat but a critical part of the redemptive plan, ensuring that God's justice was satisfied and that many could be redeemed from their sins.
