As I said, as long as I can conceive of a being that can do more than God, no matter what God can actually do, God is not the greatest or most powerful or omnipresent, because I can create a being that is +1 of anything that God can do.
However, if all 8 billion humans can commune with God at once and also every being of the universe can be in constant communion with God at once, how much more omnipresent does God need to be?
But that’s the point. It is not possible to conceive of a being that can do more than God can do, because God, being Infinite, can do anything and everything.
