re: What do people get out of going to church on Easter once a year?

I guess it depends on your definition of power. Can god move mountains or create things or do anything he wants? Yes. But no he cannot associate with sin because that would be a contradiction of his purity and holiness making him no higher than us. If he were no higher than us then he would have no ability to judge us so he must be sin free. He also must be consistent otherwise he again would not be a qualified judge. So yes god is limited in that he cannot do wrong.
