PabloSerna,
This is from St. Aquinas to you. Here he believed everything that St. Augustine believed. Augustine was his hero.
"Clearly predestination is like the plan, existing in God's mind, for the ordering of some persons to salvation. The carrying out of this is passively as it were in the persons predestined, though actively in God. When considered executively in this way, predestination is spoken of as a 'calling' and a 'glorifying', thus St. Paul says, Whom he predestinated, them also he called and glorified'. (164)"
Aquinas in the Summa
"By its very meaning predestination presupposes election, and election chosen loving. The reason for this is that predestination, as we have said, is part of Providence, which is like prudence, as we have noticed, and is the plan existing in the mind of the one who rules things for a purpose. Things are so ordained only in virtue of a preceding intention for that end. The predestination of some to salvation means that God wills their salvation. This is where special and chosen loving come in. Special, because God wills this blessing of eternal salvation to some, for, as we have seen, loving is willing a person good, chosen loving because he wills this to some and not to others, for, as we have seen, some he rejects. (168)" Aquinas in the Summa

(168)" From the Summa as well.
And this is how Calvin and we Reformed explain it as well to be the passive will of God for reprobation who choose not to be under Christ but remain under Adam. "Special, because God wills this blessing of salvation to some," as Aquinas puts it.
The fact that God wishes to give grace and glory is due simply to His generosity. The reason for His willing these things that arise simply from His generosity is the overflowing love of His will for His end-object, in which the perfection of His goodness is found. The cause of predestination, therefore, is nothing other than God's goodness. (Providence and Predestination, 116)
And so what about the place of free will?
"God does not act on the will in the manner of one necessitating; for He does not force the will but merely moves it, without taking away its own proper mode, which consists in being free with respect to opposites. Consequently, even though nothing can resist the divine will, our will, like everything else, carries out the divine will according to its own proper mode. Indeed, the divine will has given things their mode of being in order that His will be fulfilled. Therefore, some things fulfill the divine will necessarily, other things, contingently; but that which God wills always takes place." Summa
We explain the will the same way. For it cannot override God's will. Therefore, the freedom of the will as Jonathan Edwards described it, is just like Thomas Aquinas here.
