In my theological world before time began God choose the Probability of Possibilities over Simple Foreknowledge. The way I see God is Booby Fisher and I am at best an Average checkers player much less Chess. So God as Bobby Fisher has no reason for concern with any moves I might make in a feeble attempt to defeat his unfolding game plan.
Booby Fisher God can wait for my Libertarian free moves and still calculate The Probabilities of all Possibilities. Why need to know my moves and His moves after all he’s the chess champion not me. As Joe Black says in the movie named Meet Joe Black “Multiply it by infinity, and take it to the depth of forever, and you will still have barely a glimpse of what I’m talking about.”
So never say That my Open Theism makes God less, as I see it, “Multiply it by infinity, and take it to the depth of forever, and you will still have barely a glimpse of what I’m talking about.”
