How do we know that Jesus' death was predetermined?

Scripture indicates that Christ's sacrificial death was not an unexpected event but rather a fulfillment of divine predestination. In Matthew 20:18-19, Jesus foretells His betrayal, condemnation, and crucifixion, emphasizing that these events shall occur as part of God's sovereign plan. This theme resonates throughout the New Testament, where we see that the Lamb was slain before the foundation of the world (Revelation 13:8), reiterating the biblical doctrine of predestination. Christ's crucifixion was ordained to satisfy divine justice and provide atonement for His elect, thus ensuring that His sacrifice was not in vain but accomplishes the full redemption of those for whom He gave His life.
