How do we know the crucifixion of Jesus was necessary?

The necessity of Jesus' crucifixion is rooted in the fulfillment of Old Testament prophecies and God's sovereign plan for redemption. As stated in Isaiah 53, the Messiah was to be 'wounded for our transgressions' and 'bruised for our iniquities,' highlighting that His suffering was predetermined to atone for the sins of His people. Additionally, in Luke 24:25-27, Jesus Himself explains the Scriptures about Him, reinforcing that His death was essential for the salvation of those chosen by God. The crucifixion is the culminating act of Jesus' earthly ministry, satisfying divine justice by bearing the full weight of God's wrath against sin on behalf of His elect.
