So, if someone should ask, “Why did God later give his laws to Moses?” I would reply that it was in order that people might realize how sinful they were. Those laws were valid until Jesus came. He was the descendant that God was referring to when he made the promises to Abraham. The laws were given {God gave his laws} to Moses by God’s causing angels to speak to him. Moses was the mediator, the one who told the laws to the people.
