For God everything is possible. Outcomes are His creation, not His choice. Choices are in the realm of uncertainty. Whatever God does it is certain. He doesn't choose; He creates. "Let there be light" is not a choice between light and dark; it's a command. "We shall make man" is not a choice but a purpose-driven act; God was not choosing between making man or not making a man. There is no doubt in what God does. And if God wants different outcomes to be simultaneously true, He can make that too; He is not constrained by your logic. You have to think apophatically in order to know what God is not so that you may perceive what God is.
Obviously you are not a painter of landscapes or portraits..
You could paint the same scene at different times and the scene/result would not come out or appear exactly the same..
To the Observer or to the Creator.. Chance or choice are wonderful vestiges of eternity..
"Matter/mass" does not look so dense when looked at with Quantum Mechanical eyes.
Energy is matter and matter is energy.. you spread them around like paint on the Canvas of the Universe and you have a self-portrait of God.. This metaphor is pregnant.. The Spirit(s) of God are very artistic.. Choice is a wonderful thing.. it bridges dimensions.. I paint landscapes of lighthouses.. most of which exist only in my mind, and two dimensionally of course(the painting)..
Alright, I'll try this from a different angle. In light of "God does not make choices", how is it determined who gets into Heaven? Do we pass a test and then God is obligated to let us in?
In addition, I assume your position is that Jesus Christ did NOT choose to die for us on the cross. Since you are such a strong proponent of human free will, I find it odd that you are denying free will to God. If God does not choose, then He does not have free will.
