How do we know Christ's death was necessary for salvation?

The necessity of Christ's death for salvation is rooted in the theological principle that life arises from death. In John 12:24, Jesus teaches that 'except a corn of wheat fall into the ground and die, it abideth alone: but if it die, it bringeth forth much fruit.' This analogy illustrates that through His death, Christ provides life to believers. His death satisfies the demands of divine justice, allowing sinners to be reconciled with God. As the Lamb of God, He bears the sins of humanity, fulfilling prophecy and making salvation possible for both Jews and Gentiles, drawing them into a new life through faith in Him.
