Do you know why Jesus had to be God and Man?
In Christianity, God made covenants with humanity (divine “contracts”). Deuteronomy 28:1 says “If you obey…. I will bless you” and 28:15 adds, “If you do not obey…. curses will come.” From the start, humans owed God perfect righteousness. Genesis 2:17 shows the original command, and after sin entered, Romans 5:12 says, “Sin came into the world through one man.” Now every human falls short (Romans 3:23) and is unable to obey God’s law (Romans 8:7-8). So we still owed perfect obedience, but no longer the ability to give it, creating a debt only Christ could resolve.
Because the covenant was broken by humans, a human had to fulfill it. Humanity needed a representative who could stand in our place just like Adam represented us in the fall. The penalty for breaking the covenant was death, so only a real human could die as a substitute for other humans. But the human had to be without sin, or the sacrifice would be imperfect. Only God himself is sinless, but only a man can die.
Since the covenant was between God and man, God became a man to repair what humans broke. And he remained fully God so he could fulfill the covenant perfectly, without sin. God provided the only mediator capable of standing on both sides of the covenant fully representing humanity, fully satisfying divinity, fully restoring what we could never fix ourselves.
