God makes a covenant parallel to his covenant with Abraham with the kings of Israel, represented by David. God is far more generous to us than we think we can be to him. The King of Israel became the representative of the people to God, and since Israel was the representative of the World, the king was the representative of the World. It makes sense then that Jesus’ righteousness becomes the righteousness of the world. Just like with Israel, God is incredibly patient with his kings (who are mostly terrible) until Jesus comes. Because of Jesus, God’s love for us is 100% set in stone forever.
