Oh now i see what you meant by God holding us to a higher standard of morality than himself. Its a theodicy question you are getting at. Yes that is the hardest question of all. It might be the one I would ask God if I only had one question I could ask.

Job, in the Book of Job asks the same question as his fortune is gone, his family is dead and he is lying in the mud with his skin falling off. Job is demanding an explanation from God as to why such misery and suffering could exist in a world made by a loving and all powerful God (the basic question of theodicy). God finally shows up and gives a rather pyrotechnic answer that can be summed up simply by "Shit Happens".

By that answer, God is saying that the universe (and especially man) is capable of cooking up plenty of conditions for misery and suffering without God's help.
