Eternal covers it temporally, but spatially one could be omnipresent yet not infinite. That is, if space was limited, one would not be infinite in space.
So this is an argument both for all space (not necessarily in this universe alone) and for God: That he is spatially extended outwards in all directions infinitely.
I think we have three general ways in which we can interpret omnipresent (and of course, countless details).
One of which is the direction you have seem to go in (if I don’t misunderstand), in which omnipresence is somehow a physical trait. A pantheistic view of omnipresence, so to speak – all of existence IS God – God IS all of existence.
Another possibility is a God with omnipresent vision, which, essentially is omniscience combined with omnipotence. Think of the Wicked Witch of the West, looking in her crystal ball to see Dorothy (though to a much greater scale, of course). Though SHE is not there, by seeing what is there and having her power able to reach where she is, she is
effectively there.
The way I imagine this God in my head is a spider on a web. Without looking, a spider can tell exactly where a bug in his web is, how much it weighs, how large it is, how much it is struggling, how much energy it has etc. all from the vibrations the spider feels on the web. God is that spider on a vast multi-dimensional web made up of, for lack of a better word, the aether. By picking up on the vibrations in the aether, he knows everything that is going on. He is a being that has perfected the Vedic ideal of tapping into the prana and akasha.
The third option I see is, as I pointed out earlier, a God without corporeal body. The “holy-sprit” as it were. God IS the prana. He is not all, but pervades all.
Consider that if one is perfect in every category, that to change at all is to admit of a defect. One cannot move from one perfect state to another perfect state, without passing through imperfections. Similarly, things such as spatial infinity admit of no change.
I disagree.
Although I am not certain that “perfection” is something that exists outside of bounds (i.e. something can be perfect FOR this or that, but not singularly perfect in and of itself as a trait) – which is why I did not include “perfect” in my opener – if something were to be perfect, that thing must certainly be ideally adaptable to all situations, and foreseeable & unforseeable futures and all possible changes. It must be in a constant state of flux and have the ability to adjust any aspect of itself instantaneously.
If something is eternal, does not this speak of necessity? Existence could not be conceived of existing without it, no? For that is the only reason something would not be subject to the viccisitudes of existence, no?
I actually find the account of creating very suspect. For what would a God who is omnipresent create? If he is all ready present in all things, then it stands to reason that space is all ready ultimately existent.
Definitely not. Also, in an eternal system one cannot have a rightful first cause. An eternal system with a first cause has a beginning, yet eternity can neither have beginning nor end.
I think this all goes back to what I said about omnipresence.
If you do not see God as a pantheistic entity, none of this would necessarily flow from having an eternal nature.
If you consider God to be eternal, and separate from his creations, that is another story.
If God is eternal, but not all, he could have very well decided to create the physical universe within the void, no?
