For it would serve to explain not only God's knowledge of the future, but divine providence and predestination as well".[9] Under it, God retains a measure of divine providence without hindering humanity's freedom. Because God has middle knowledge, he knows what an agent would freely do in a particular situation. So, agent A, if placed in circumstance C, would freely choose option X over option Y. Thus, if God wanted to accomplish X, all God would do is, using his middle knowledge, actualize the world in which A was placed in C, and A would freely choose X. God retains an element of providence without nullifying A's choice and God's purpose (the actualization of X) is fulfilled.
