God is everywhere. This is the common idea of omnipresence. But it goes further than this. To just say he's everywhere tends to be interpreted in terms of spacetime. Like, God is in the house and the tree and the car. It makes sense.
But there's a key component we need to consider. God can't be partly anywhere, because he is absolutely one within himself. Nor can only a part of him be somewhere, because all of him has to be there in completion.
So then think of it this way. The entirety of the whole of God is in the house, while simultaneously the entirety of the whole of God is in the car, while simultaneously the entirety of the whole of God is in the tree.
If you can visualize this at all in your mind, it is mind blowing. It defies and breaks all the laws of physics. We would claim, well, if all of God is in the car, how can he also be entirely and fully and completely in the house at the same time? Normal laws of spacetime would not permit this.
We'd normally say, well, if all of something is somewhere, none of it can be anywhere else. But this is spacetime reasoning. This is not how God thinks or how he functions and exists.
God transcends all the laws of separation. Therefore, God CAN be entirely in one place, and in another place, and in another place, all at the same time. And he is not only partly there, but totally there. His entire attention, if you will, all of his being, is fundamentally in EVERY location at the same time.
This is not the same thing as saying that he is just a very big object which has some parts of it spanning across space, where some of the outermost parts are in one location and some of the other parts are in another. It is not the same thing as saying God is a universe whereby it is very big and God's left hand is over here and God's right leg is over there. God is not space or time.
In fact God utterly transcends space and time, being omnipresent and eternal. The laws and limits of space have no effect or bearing whatsoever on his nature. All of God CAN BE ENTIRELY in one place, while also being ENTIRELY in another simultaneously.
This is somewhat akin to a "blur". If you take some object and you totally blur it, spreading it out, the object seems to be everywhere at once. You can't easily put a finger on it and see the original shape, it has lost all form in the blurring. But all of it is everywhere. It's sort of like being out of focus.
The thing is though, that it is the laws of spacetime that cause the object to not be identifiable in its clear form, at the same time as being distributed. And this does not apply to God.
God is not out of focus. He isn't sort of ... distracted and distributed and diffused and unlocalized. ALL of him, his entire attention, is in one place, AND all of his attention is in another place. He breaks all the laws and requirements of spatial separation. This means he is simultaneously abstract ie out of focus, AND entirely focused.
Ultimately not only is God everywhere, but ALL of God is everywhere. This in turn means that God is impersonal, AND fully personal, at the same time. He is impersonal in that there is no difference between who or what he is in any particular location or part of himself, treating everything in the same way. And he is ENTIRELY personal in that his entire being is in every part of himself and is fully present for every part.
Since God DID create a very large number of personal beings who each are a whole and fully created being, God has a COMPLETELY personal relationship with all of them individually and specifically. But at the same time, their relationship is open and shared with all others, and is equal to all others, making it entirely IMPERSONAL.
God loves YOU fully, and loves your brother's the same way.He therefore has an entirely personal AND impersonal relationship with all his creations.
