The biggest problem I have with this, with all due respect, is that this plan would seem to lack much in the way of either infinite love or inscrutable wisdom, not to mention the fact that it doesn't agree with the older churches as well as many others. Unless man's will is involved in some way, however tiny, beginning with Adam, in his participating in choosing the good over the evil, in heeding God's voice over the adversary‘s lies, pretty much free from constraint or overriding influence, then the entire drama of life, here in this exile from Eden especially, appears to be a shallow, fruitless, and futile game. God could have and may as well have averted all the evil that has ensued in this world since the Fall, and simply brought about the good-for some-of electing them to salvation/heaven and the evil-for the rest-of predestining them to damnation, from the beginning.
Because unless man’s will is involved there's no purpose to life between birth and our final destinies, other than to fall one way or the other in the end depending on God's whim. And that just plain puts the cart ahead of the horse. We don't even know with certainty who's saved and who's not, who will persevere and who won’t, for that matter.
Either way, with this theology, with man’s will uninvolved or determined, God effectively becomes the sole author of sin/evil it would seem. But if I, as an individual human being, have a choice in the matter, regardless of whether or not God in His omniscience foreknows that choice, if I can learn from the experience of good and evil, with the help of revelation and grace, to choose the good alone, then my salvation hinges on God’s saving grace, without which salvation is completely impossible, but not without my consent, my cooperating in working out my salvation with He who works in me.
This, it seems to me, contains a great deal more love and wisdom, and is consistent with our experience in life in general, with consequences resulting from our choices. In this God has a purpose greater than simply saving some otherwise worthless wretches deserving of hell. Rather His whole plan from the beginning would be to ultimately bring about a greater good out of the evil of the Fall, as a part of ultimately, patiently, molding and perfecting His creation-us-whom He so greatly loves and desires to come into union with Him. As we increasingly align our wills with His, as we become transformed into His image, our justice increases. And in the end He judges how well that’s been accomplished.
