How do we know that Jesus' death was necessary for our redemption?

Jesus’ impending death, though perceived as a loss by His disciples, was critical for their redemption. In John 14:2-3, He states, 'I go to prepare a place for you... I will come again and receive you unto myself.' This underscores His role in securing salvation. He must suffer and die to repair the broken relationship between God and humanity and to prepare an eternal home for believers, demonstrating that His sacrificial death was both purposeful and necessary for God's plan to bring about redemption and eternal fellowship with Him.
