This post is a response to another post, which presents an argument for why there can be at most one god. I recommend reading it first: Unstoppable Objects, Immovable Walls, and Omnipotence by JC.
I agree that having two truly omnipotent gods is logically impossible, and of course the Christian view is that God has such power that there is no room for another god: “I am God, and there is no other.” (Isaiah 45:22) But what about weaker gods, such as the Greek pantheon, or the Mormon view (if I understand it correctly) where each god has his own universe? And what exactly does it mean to be omnipotent?
The regional gods that nations previously worshiped are easy to dismiss, because even if they existed and one was mad at you, you could just move somewhere else to escape him—hardly a fearsome god. And any god with demonstrably finite power warrants only limited respect, because in theory you could defy such a god and still escape. (Whether such beings deserve to be called gods is simply a matter of terminology.) I’m not inclined to worry about gods like these, not only because I don’t believe they exist, but even if they did, maybe I could ignore them and still evade their finite reach.
Harder to discount is the concept of one god per universe. In such a system, we would see the effects of a god who is apparently omnipotent but is in fact limited to perhaps a four-dimensional subspace of a wider multiverse. The only non-biblical argument against this that comes to mind is the odd situation that would result: many, perhaps infinitely many gods and universes, all isolated from each other. But where did this community of gods come from? That would raise the question of whether there is a God above all these gods. Perhaps the gods of the universes are merely a very powerful race that owes its existence to the true, omnipotent God. So again, the remaining options would be one true God or no truly omnipotent gods at all. But an observer in any given universe might see the effects of a what appears to be an omnipotent God but is actually a finite being.
I still have some lingering questions about what it means to be omnipotent. As JC’s post rightly states, God cannot will a condition that logically contradicts itself, such as placing himself both inside and absolutely not inside of a wall at the same time. This does not lessen his omnipotence, because the requirement to be somewhere and also not somewhere at the same time is a nonsense statement. But was God able to choose his own nature? For example, according to the Bible, God is infinitely good. For this to be true, God can never perform an act which is not good, such as lying. So God cannot be both infinitely good and a liar, but did he have the opportunity to choose between these two options? If we take God to be infinitely good, then if there was ever a choice, it has already been made and cannot now be reversed. This would mean that God, although omnipotent, is incapable of lying. But is this restriction intrinsic to God’s nature, or did he choose to be this way? In other words, is God unable to lie because a lying God is a logical contradiction, or because he once chose that he would never lie?
As for why the universe (or multiverse) should have exactly one God, I have one observation. Either the universe has always existed (so that energy and the laws of physics are eternal), or it was created somehow. This creator could be a single God or a community of gods who are all eternal but are all bounded by their allocated subspace of the multiverse. The latter option seems implausible, and I see no reason why the laws of physics should have existed from eternity of their own accord. Even if all of the material universe and the laws of physics can be explained and summed up in a single, all-encompassing Law, why did this law ever exist, and what gave it the opportunity to act? Did this Law of Nature contain the impetus to create a universe to exert itself upon? In other words, did the Law of Nature will the universe into existence? I find it much easier to accept that the source of this ultimate will is a living being: a single, infinite, omnipotent God who is the Source of all other things, the God who, when asked to give his name, needed only to say “I AM.” (Exodus 3:14) His eternal nature is still unexplainable, but I think this is the most likely option.
I might go so far as to say that this single God, the I AM, is in a sense the ultimate Law of Nature—not that God is a mere force, but that the fundamental workings of the universe ultimately stem from God Himself. The laws of physics tell us of forces that drive the universe (gravity, electromagnetism, etc.) but can tell us nothing of why they exist. I contend that God upholds these forces and laws by his will, that it is God who gives spacetime its breadth, the forces between galaxies their strength and the laws of physics their authority, that God, although not the most detailed answer to the scientist’s basic question, “How?” (math does that job already), is forever the answer to the basic human question, “Why?” And this is one of the reasons why the primary goal of my life is to learn more about this God and to love and serve him.
