God’s covenant promises of unit 3 are beginning to be worked out. In Genesis 12 – Exodus 18 we see how God begins to make a people for himself by miraculously granting Abraham and Sarah children and then many descendants. We see again and again that evil, unworthy persons become God’s people and it becomes clear that it is God who saves and that no man can boast. We see how God rescues his people from slavery in Egypt by substitution, by conquest and by defeating their enemies. Once freed from slavery God’s begins to bless his people by giving them his law and by being amongst them. Things are beginning to look up, but there is much more to be fulfilled.
