Answer: Because the just penalty for sin is infinite and eternal, only God could pay the penalty, because only He is infinite and eternal. But God, in His divine nature, could not die. So God became a human being in the person of Jesus Christ. God took on human flesh, lived among us, and taught us. When the people rejected Him and His message, and sought to kill Him, He willingly sacrificed Himself for us, allowing Himself to be crucified (John 10:15). Because Jesus Christ was human, He could die; and because Jesus Christ was God, His death had an eternal and infinite value. Jesus’ death on the cross was the perfect and complete payment for our sin (1 John 2:2). He took the consequences we deserved. Jesus’ resurrection from the dead demonstrated that His death was indeed the perfectly sufficient sacrifice for sin.
