18. Let us now look to the expression, “It is not of him that willeth, nor of him that runneth, but of God that showeth mercy.” For our opponents assert, that if it does not depend upon him that willeth, nor on him that runneth, but on God that showeth mercy, that a man be saved, our salvation is not in our own power. For our nature is such as to admit of our either being saved or not, or else our salvation rests solely on the will of Him who, if He wills it, shows mercy, and confers salvation. Now let us inquire, in the first place, of such persons, whether to desire blessings be a good or evil act; and whether to hasten after good as a final aim be worthy of praise. If they were to answer that such a procedure was deserving of censure, they would evidently be mad; for all holy men both desire blessings and run after them, and certainly are not blameworthy. How, then, is it that he who is not saved, if he be of an evil nature, desires blessing, and runs after them, but does not find them? For they say that a bad tree does not bring forth good fruits, whereas it is a good fruit to desire blessings. And how is the fruit of a bad tree good? And if they assert that to desire blessings, and to run after them, is an act of indifference, i.e., neither good nor bad, we shall reply, that if it be an indifferent act to desire blessings, and to run after them, then the opposite of that will also be an indifferent act, viz., to desire evils, and to run after them; whereas it is certain that it is not an indifferent act to desire evils, and to run after them, but one that is manifestly wicked. It is established, then, that to desire and follow after blessings is not an indifferent, but a virtuous proceeding.
