The Arrogance of God
If God is so all-mighty, it is only so because he can't help it. Any God is supposed to be all-mighty - that is what defines a God. Why would God want his creatures to praise him for his greatness when it was no mean art for God to create the universe? He simply did what he was capable of. It would indeed be very arrogant of God to expect his creation to praise him just because he is so great - he didn't ask to be God after all.
