All Knowing God proves problematic

I could end world hunger by snapping my fingers but I choose not to.

They wouldn't have to share if everybody had enough. Think manna.But my point was that anybody can say, "I could do that but I don't wanna." The evidence that you can is that you do.

Then what good is He?And my point, again, is that anybody can say he's omnipotent - but if he doesn't demonstrate his abilities, his words are empty.The same applies to ominscience, as per the topic. I can say I know everything there is to know about geology but unless I can demonstrate that I know something about geology, my claim is empty.So I'll ask, yet again, why is it that those who claim to commune with God, He Who they claim to be omniscient, don't seem to know anything special? If He isn't communicating something that requires omniscience to know, what good is communion?
