While I was reading this I thought to myself: Is God human? Well, God isnt a human obviously but he has the good characteristics of human. He can be happy. He cares for us. He lavishes us with Gifts if we have behaved. He gets angry with you do the wrong thing. He was so angry that he threatened to do this and because he is so forgiving, he has given us another chance to do whats right.
He was so angry because the people did not know of him so insted of praying for something else, the people of Isreal automatically assumed that calf was the God that has saved them so they decided to worship it but in my opinion I think they did not know any better because everyone one of them were new believers.
God himself thought they knew better then that. The people of Isreal had automatically broken one of the ten commandments and do do this is not good atall.
