St John of Damascus: Those things which do not depend upon us...
One should note that God foreknows all things but that He does not predestine them all. Thus He foreknows the things that depend on us, but He does not predestine them - because neither does He will evil to be done nor does He force virtue. And so, predestination is the result of the divine command made with foreknowledge.
Those things which do not depend upon us, however, He predestines in accordance with His foreknowledge. For, through His foreknowledge, He has already decided all things beforehand in accordance with His goodness and justice.
