God Appeases Himself

I'm still stuck on the concept of God doing what only God can do.  It both fascinates and puzzles me because now I can see it in so many ways I never realized before.  I am doing a Bible study by Kay Arthur and in it there is a statement close to this: Reconciliation is unique to the Christian faith.  Every other religion teaches that man has to appease God.  Biblical Christianity teaches that God appeases Himself, supplying what is necessary to reconcile us to Him: His Son's blood for forgiveness of our sins.  I never made that particular comparison to the world's thinking and God's doing.  God appeases Himself! Awesome!
