Molinism sees God's knowledge as comprising logical moments, placing God’s decision to create after the moment of God’s hypothetical knowledge:
In the Molinism schematic below, worlds that could be created are shown as ‘O’
Moment 1: .... OzOzOzzzzzzzzzOzzOzzzzOzzzzzzOzzzzOzzzzzzO...
Natural Knowledge: God knows the range of possible worlds (what could be). The content of this knowledge is essential to God.
Moment 2: ... zzzzzzzzzzOzOzzzzzzzzzOzOzzzzzzzzzzzO...
Middle Knowledge: God knows the range of feasible worlds (what would be). God’s [hypothetical] knowledge of what every possible free creature would do under any possible set of circumstances and, thus, knowledge of those possible worlds which God can make actual. The content of this knowledge is not essential to God.

Moment 3:… zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzO
Free Knowledge: God knows the actual world (what will be). The content of this knowledge is not essential to God.
Craig and others refer to the counterfactuals of creaturely freedom (CFs): Knowing what any possible agent would do in any possible circumstances, God can have complete providential control over the events that occur by knowing how the history of the world would go given any creative decision He might make about which circumstances to cause to be actual, and by then making that initial creative decision. Yet human libertarian freedom is obviously also maintained.
But, foreknowledge is grounded in something that actually happens, and it is the occurrence of that future event that sanctions the foreknowledge of it. On the other hand, whatever grounds the truth of counterfactuals of freedom is something other than an actually occurring event. The indeterminateness of counterfactual states of affairs in virtue of which counterfactuals of freedom are true is therefore of a wholly different order from the indeterminateness of future states of affairs in virtue of which future factuals of freedom are true. Though the latter are not yet determinate, they nevertheless will be.
Even granting that there are some CF’s with actual (true) antecedents whose truth might in principle be determined by actual agents it seems to be such that God could not know them pre-volitionally, if He must directly perceive their grounds. For until God decides which agents and which circumstances to cause to be actual, there aren’t any actual decisions that God could in principle know as the grounds of these CF’s. Since middle knowledge is meant to be the aid by which God determines the actual world, and yet it seems as if He could not have this knowledge logically prior to determining the actuality of a particular possible world, “middle knowledge” seems both incorrectly described and unhelpful for providential creation decisions.
I believe that the Molinist view of providence should be rejected because there are good reasons to think that there are not any (and certainly not enough) true counterfactuals of freedom. According to Molinism, foreknowledge is nothing more than the causally impotent byproduct of God’s creative act of will.
