One of those attributes of God is his ability to be everywhere at all times. I'm not debating that it is an attribute of his, I'm just wondering how we know that.
I ask, because I've been going through a question of my own recently - If God is omnipresent, how can hell exist? After all, hell is by definition, that one place that God is not. But, if God is everywhere, how can there be a place that he is not?
My favorite answer to that question comes from C.S. Lewis' The Great Divorce, in which he describes hell not as a place of fire and brimstone, but rather an infinitely empty, substance-lacking smallness. The journey from hell to heaven that his characters make is not from "down" to "up" from rather from "small" to "big" and "weak" to "strong."
I really like using that idea of hell, since it seemingly answers the idea that hell is merely a place that is, itself, so small and insubstantial that it isn't God's lack of presence, but rather its own insignificance that causes God's presence to feel so lacking.
In order to test that assertion, however, I want to make sure that I am correctly stating the postulate - namely that God really can be everywhere at all times. What is its biblical basis, and does God presence exist in hell?
