Yes, omnipresence is a characteristic of God, that's what I'm saying. Hence, there is no place, outside or inside of time and space, where (and when) God is not. In fact, there is, was, and will be nothing but God -- God is all there is. It's plain as day why anyone who sees thus clearly can say, "Before Abraham was, I am."
I understand that you believe and have confidence in your salvation while on Earth, but you still testify only to your faith and confidence. I say that you can enter and live in Eden, Kingdom of God, Heaven, etc. even before you die. And I don't have to believe or have confidence in that -- I know it for a fact.
