I like to think that if Jesus was divine that his death was a payment, not for everyone's sin, but for God. I mean that God had a permanent covenant with the Chosen People. He chose to change that covenant to include all people. His justice required that he make a payment to the chosen people and that payment was the sacrifice of Jesus in God's place. It seems a much simpler interpretation than the convoluted one about how people could never "pay the piper," so God did it for them.
