How do we know Jesus' death was necessary for salvation?

In discussing the necessity of His death, Jesus illustrates this using the metaphor of a corn of wheat in John 12:24, stating that unless it falls to the ground and dies, it remains alone. This signifies that His sacrificial death is essential for the redemption of His people. Much like a seed that must die to produce a harvest, Jesus’ death was predestined by God to bring about salvation for many. The sovereignty of God ensured that this death was not accidental but a crucial part of His divine plan to glorify Him by bringing humanity back to Himself, showcasing His grace and mercy through Christ.
