I think the key to understanding this is that Scripture says God is unchangeable. Thus, He creates everyone as one "NOW" in the mind of God -knowing what decisions will be made FREELY by our decisions and without taking away the ability for us to CHOOSE or God would be changed
From Saint Thomas Aquinas...
God is altogether immovable, which is confirmed also by the authority of Holy Scripture. For it is said: I am the Lord and change not (Mal. iii, 6) ; With whom there is no change (James i, 17); God is not as man, that he should change (Num. xxiii, 19).*
There is, though, that curious event where Moses changed God’s mind . . . according to God’s own Word.
Thanks for that perspective. As always someone here says it better than I.
