I suppose I should start with what I think we all believe to be true.
God does not indwell the unsaved person.
2 Corinthians 13:5 KJV
Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?
God exists at all times at the same time. God is present today and also exists prior to Abraham at this moment.
John 8:58 KJV
Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am.
The part I'm not understanding is if God is not in the lost person, how could you say he is everywhere?
I see now rereading psalm 139:8 that the passage could be believed to mean that if David were to be lost, dead and in hell, God would be there.
If that is what the verse is saying, I could understand the belief that God is present everywhere and even in the presence of evil. I still would not understand how to reconcile God not being in the sinner and being present everywhere. If that is what the bible teaches, I am not more wise than God. He is right. I am wrong.
