The Angel of the LORD

Cary Cox, from Genesis 16:7 (Genesis Study 35). Who is the angel of the LORD? He appears in Genesis 16, and we meet him all over the Old Testament. He is both a messenger sent from God, and he is also God. How can this be? And how does this prepare us to understand the coming of Jesus in the New Testament – the Word who became flesh, who was with God and who was God?
