I've heard a few stories, like Left Beyond Quest and the plot of the game Messiah, in which humanity attempts to fight/conquer Heaven and Hell. The general consensus is that, since there aren't any omnipotent or omniscient demons that Christians believe in, it should be doable to conquer Hell. However, when it comes to fighting or conquering Heaven, the big obstacle is God.

So this is my question: do any Jewish, Christian, or Muslim documents reveal any weaknesses that could be exploited? And if not, are there any logical weaknesses to such a being, which could be extrapolated from what IS known?
