Can the omnipotent God create a stone which he(she?) him(her?)self Cannot carry?
(Note: blasphemy added by levik. Disregard if offensive)
God created EVERYTHING. That includes logic. Thus, he is not subject to
that which he created save for His own will. Since such an action
serves no purpose in the big scheme of things, God will not.
God is also not subject to time, having created time. Since God doesn't
change, this includes the changing of His will, which at the moment
does not include worthless display.
Thus, in a sense it is possible to say He cannot violate his own will.
Solution: No.
