You're asking questions that probably only God would know. I think my best guess is he is like a universe unto himself that his own consciousness can move around in and interact with. Basically I think if his mind is really infinite then within his own thoughts he has infinite space. If he has already thought of everything possible then that is a lot of "things". To God all these things could be real and simultaneously existing. He divides between them to make something that actually makes sense; such as this universe. Otherwise it would all be jumbled together in chaotic form. So then I think God made this universe from out of what is called "chaos". God used his word to divide between the things that could be and the things he decided actually should be. This way he brought "order" to the chaos and the universe was born.
I'm not stumbling anything. I didn't realize you were challenging me like this. I thought you were genuinely curious.
Well regardless of what you might think of me, I AM genuinely curious....and sometimes I NEED to get a little, as you say, "challenging" in order to get SOME (not necessarily you, of course) but SOME complacent people to actually THINK a bit about what they believe.
Because the scripture makes it clear that God makes everything by his spoken Word. So he just speaks and it exists. That's a strong indication that he's outside it all. Or to be precise we might be inside of him.
Over the years I have been kicking this religious business around, I come to the conclusion that what is written in the Bible, that so many believers have come to believe IS the actual words of their God, is in reality, nothing but a collection of ideas, musing, theories, postulations, etc etc of what amounted to back then as a bunch of indigent, nomadic, uneducated Goat-herders, and NOT something which I should place any sizeable amount of trust in its veracity and it validity.
BUT, I also realize and admit, that it IS all we have and need to make the most of it that we can.
