He was addressing my examples, in which I tried to simplify how God sees our reality - he understood what I meant to say, and he was right that it could be confusing. Your understanding of God is such a simplified view - you cannot yet grasp the concept of what “eternal” means.
I mean, I think no one can know for certain what eternity means, but some of us are at peace knowing it is beyond our **current **capacity to understand things.
How God’s knowledge of what is to come is possible? The explanation has already been given: God lives outside time and space. He has existed “before” Creation. (and this “before” I use as a figure of speech, as time didn’t exist “before” creation)
“Whatever” God is, is beyond our complete understanding. How it works? How is it sustained? What is God made of, if not matter? That is all beyond us, for now.
This point in your post:
“God cannot sustain the creation if he is in state of timeless”
This point shows why you have difficulty in understanding the concept of a timeless God.
Precisely because He is beyond time (timeless) is that He can maintain a timed existence. He created time for us, for everything that was created, and not for Himself. He doesn’t need time to exist, He just “is”.
To use a silly analogy, imagine that God = humans and creation = car.
We created gas to give “life” to cars. Cars can’t function without gas , but we ourselves don’t need gas to exist.
Likewise:
God created time to give existence to creation. Creation can’t exist outside of time*, but God himself doesn’t need time to exist.
*(for now and as far as I know)
