I think God probably reserves the privilege of being spontaneous in His moment of decision making as He continuously goes about the authoring of all life. Spontaneous may not be the best word. But He already knows - you could say, foreknows - what He wants. I picture then an omnipotent and omniscient God (an all-powerful and all-knowing God) having infinitely sufficient means to pull off whatever He needed to pull off in order to achieve His pre-determined end result. I suppose He looks down on the whole realm of possible courses of action and choses, or, in the absence of any good possibilities to chose from, just "creates" His own possibilities; foreknowing already, what He wants, all of the possiblities that will present themselves, and then, exactly what He needs to do to get there to His chosen outcome. Enacting right now, in the moment, things of the moment, having prepared them from the beginning of time, and preparing then, as well as now, for things nearly an eternity away.
Of course this would have to be a gross oversimplification. But I truly believe that, in part, the process could go exactly as just described.
We know God does have a different relatioship to "time" than us, but exactly how, we don't know. It's one of those things we can't know yet. We do know His relationship to us is "living and active".
For the word of God is living and active and sharper than any two-edged sword, and piercing as far as the division of soul and spirit, of both joints and marrow, and able to judge the thoughts and intentions of the heart.
I'm convinced that the present and future may be almost as fresh to Him as it is to us; "fresh" being "newly brought into being". Things in the present must be the product of a fluid and ongoing process of Him effecting a Plan. Or no?
The end plan being a "new" product of ongoing deliberation, preparing, pre-planning, deciding, predetermining; all the while knowing ahead of time what outcome He will bring into being.
There are almost an unlimited number of ways to get from Rhinelander to LA. Leaving Rhinelander one could go over through the Twin Cities and then head west. Or go down through the Quad-cities and over. Or down through Atlanta and then over, or over through Tokyo, or Spain and then Butte, and then over. The possiblities are vitually endless. That seems to me to be the range of possibilities that God is confined to. Infinite. Limitless. Any way He wants to get there. Possibly the more scenic the better.
We all know that much has been created beforehand by Him for us to walk in. Of course, that leaves a huge dynamic of possibilities as to "how" that actually "is", and "was", and "will be".
Well I was given cause to put down in words what I envision personally as the sort of base process for God's enacting all of the details of His plan. This is nothing more than a bunch of whimsical chasing after something I can't know for sure. But I've also got to believe it's basically a sound foundational position from which to view God's enacting of His plan. It's all nothing but fear and wonderment for us anyway, cradled within the context of God's great love for those who want to know Him and follow after His words.
