OK God dwells in eternity which has no time or space.
I define nothing as with respect to only the created order.
Before His Word created anything nothing was created.
His first creative command began both chronology and matter.
God's ability to do this - to be creative, to indeed cause new matter to appear or indeed time to change is fundamental to faith.
In this He has also put a time and space barrier inside of each person and caused eternity to dwell there (Ecc3:11)
So He is not bound by or limited by in any way to the created order.
You still have not defined "nothing". Let me try to parse this out.
I think we agree on these three premises:
1. God has always existed. He is eternal.
2. God encompasses ALL of existence. He is omnipresent.
3. The universe (the created dimension) is temporal. It had a beginning.
I think you are stumbling to fully understand this point:
4. God did not create the universe
out of nothing.
The word "nothing" is the key term here. I define "nothing" to mean "outside/beyond God's existential sphere". However, since God is omnipresence, nothing can be outside of him. God completely and totally encompasses every region of existence infinity and eternally. There is no such thing as "utter nothingness" or "non-existence".
Colloquially, when we say that the universe "did not exist" before God created it. What we are really saying is that it did not exist
in that form before. Take a new born child for example. The moment before conception, that child "not not exist". However, this child did not come from "nothing". Every atom of that child existed beforehand, but they were being utilized differently.
This brings me to me last point:
5. God necessarily had to create the universe
out of Himself.
Please show me where my logic is incorrect.
