Originally posted by the Angelic Doctor: The preparation of the human will for good is twofold: the first, whereby it is prepared to operate rightly and to enjoy God; and this preparation of the will cannot take place without the habitual gift of grace, which is the principle of meritorious works, as stated above (Article 5). There is a second way in which the human will may be taken to be prepared for the gift of habitual grace itself. Now in order that man prepare himself to receive this gift, it is not necessary to presuppose any further habitual gift in the soul, otherwise we should go on to infinity. But we must presuppose a gratuitous gift of God, Who moves the soul inwardly or inspires the good wish. For in these two ways do we need the Divine assistance, as stated above (2,3). Now that we need the help of God to move us, is manifest. For since every agent acts for an end, every cause must direct is effect to its end, and hence since the order of ends is according to the order of agents or movers, man must be directed to the last end by the motion of the first mover, and to the proximate end by the motion of any of the subordinate movers; as the spirit of the soldier is bent towards seeking the victory by the motion of the leader of the army–and towards following the standard of a regiment by the motion of the standard-bearer. And thus since God is the First Mover, simply, it is by His motion that everything seeks to be likened to God in its own way. Hence Dionysius says (Div. Nom. iv) that “God turns all to Himself.” **But He directs righteous men to Himself as to a special end, which they seek, and to which they wish to cling, **according to Psalm 72:28, “it is good for Me to adhere to my God.” And that they are “turned” to God can only spring from God’s having “turned” them. Now to prepare oneself for grace is, as it were, to be turned to God; just as, whoever has his eyes turned away from the light of the sun, prepares himself to receive the sun’s light, by turning his eyes towards the sun. Hence it is clear that man cannot prepare himself to receive the light of grace except by the gratuitous help of God moving him inwardly.
