The Role of Middle Knowledge in Divine Providence

Molinism says God has this kind of middle knowledge of these counterfactuals of creaturely freedom but it's a very handy thing for him to have. It's providentially useful say. The reason that having this middle knowledge is so useful is that it makes the divine decree happen with human freedom, he knows how creatures would freely choose. And in general it is admitted that apart from a doctrine of middle knowledge it is impossible to give an account of divine providence that affirms both divine sovereignty and human libertarian freedom.
