God made a promise to Abraham that in his seed all the nations of the earth would be blessed (Genesis 22:18). He brought Jesus, the Messiah, out of His covenant partner’s descendants 42 generations later (Matthew 1:17). God never forgets His promise. He never forgets His covenant. The law, given by God through Moses, 430 years after Abraham, kept Abraham’s descendants under His protection and BLESSING, until the coming of the promised One. He kept them pointed towards Jerusalem, the center of the mystery that was hidden in God–which is Christ in you, the hope of glory (Colossians 1:27).
