If God is omnipotent then omniscience is irrelevant.  It doesn’t matter what God knows about what or whatever, IS, because what IS is utterly subject to his power.  And thus meaning—that is, whatever there is to know about anything—is utterly subordinate to what God decides things are and do at any given moment.  Because HE may arbitrarily decide all meaning at any given moment by controlling absolutely what all things are and what they do, He doesn’t actually need to know anything about anything at all.  Since He can change meaning at will and at whim, the knowledge of anything is completely subjective, and thus, at root, pointless to him.  Omniscience is irrelevant to he who has the ability to arbitrarily command meaning through plenary control of all that which exists.

But if God is omniscient then omnipotence is irrelevant.  In order for God to know everything about whatever is, then whatever is cannot be subject to a plenary power to change things on a whim.  Because in such a case, as I’ve already shown, knowledge is entirely subjective, being subordinate to his power to command meaning. Unless one knows truth which is not subject to an ability to arbitrarily change it on a whim, then one is not omniscient.  Omniscience thus renders omnipotence impossible.  If what God knows truly IS, then what it IS must be beyond his direct control.

And if God is omnipresent, then we must conclude that He exists in precisely the same place and at the same time as you and I and everyone else.  And thus, there is no place for us, or for anything about us, to be, including our own consciousness—our own awareness of and ability to conceptualize our own Self. In which case we do not actually exist…for there is nowhere for us to be since God is everywhere.  And therefore there is no one to ponder the ideas of God and his omniscience or omnipotence or omnipresence or anything else.  God’s omnipresence precludes the possibility of any actual thing, or any actual agent, outside of Him, or co-existing with Him.  He is everything and everyone, which…when you think about it really means that He is nothing and He is no one.  And in this case, there is nowhere for Him to be, either. So God’s omnipresence means that He cannot actually be present anywhere, and thus is a contradiction in terms.
