IMO once you demote God from an utterly transcendent, omnipotent, omniscient, omnibenevolent entity to a mere being among other beings, you undermine the best reasons to believe in God in the first place.
You should believe in what you think is true... not play "Make-A-God"
I agree. That's sort of the point. What reason is there to think a God who is a mere being actually exists?
God could be incredibly powerful, knowing, etc... but not this infinite magic power/knowledge level.
Some could call the state of the universe as evidence.
But the point is, if we learn at the moment of death what God's true nature is, and it's almost exactly what you thought, but not omnipotent or omniscient... wouldn't you still follow God and call God "God"? Do you love God, or do you love power and knowledge?
