But maybe somebody is asking, “Why did God give his law to his people?” This is the answer. His people kept doing bad things, so God gave them his law. And he wanted them to follow that law until Abraham’s special grand-son came. This was the grand-son that God was talking about long ago when he promised good to Abraham. You see, God gave his law like this. He used his angel messengers to tell it to a man, called Moses. That man stood in the middle between God and the people, to help those people listen to God.
