7. Wherefore we have need of zeal in every direction, and much preparation of mind: and if we so order our conscience as to hate our former wickedness, and choose the contrary path with as much energy as God desires and commands, we shall not have anything less on account of the short space of time: many at least who were last have far outstripped those who were first. For to have fallen is not a grievous thing, but to remain prostrate after falling, and not to get up again; and, playing the coward and the sluggard, to conceal feebleness of moral purpose under the reasoning of despair. To whom also the prophet spoke in perplexity saying “Doth he who falleth not rise up, or he who turneth away not turn back?” But if you inquire of me for instances of persons who have fallen away after having believed, all these things have been said with reference to such persons, for he who has fallen belonged formerly to those who were standing, not to those who were prostrate; for how should one in that condition fall? But other things also shall be said, partly by means of parables, partly by plainer deeds and words. Now that sheep which had got separated from the ninety and nine, and then was brought back again, represents to us nothing else than the fall and return of the faithful; for it was a sheep not of some alien flock, but belonging to the same number as the rest, and was formerly pastured by the same shepherd, and it strayed on no common straying, but wandered away to the mountains and in valleys, that is to say some long journey, far distant from the right path. Did he then suffer it to stray? By no means, but brought it back neither driving it, nor beating it, but taking it upon his shoulders. For as the best physicians bring back those who are far gone in sickness with careful treatment to a state of health, not only treating them according to the laws of the medical art, but sometimes also giving them gratification: even so God conducts to virtue those who are much depraved, not with great severity, but gently and gradually, and supporting them on every side, so that the separation may not become greater, nor the error more prolonged. And the same truth is implied in the parable of the prodigal son as well as in this. For he also was no stranger, but a son, and a brother of the child who had been well pleasing to the father, and he plunged into no ordinary vice, but went to the very extremity, so to say, of evil, he the rich and free and well-bred son being reduced to a more miserable condition than that of household slaves, strangers, and hirelings. Nevertheless he returned again to his original condition, and had his former honour restored to him. But if he had despaired of his life, and, dejected by what had befallen him, had remained in the foreign land, he would not have obtained what he did obtain, but would have been consumed with hunger, and so have undergone the most pitiable death: but since he repented, and did not despair, he was restored, even after such great corruption, to the same splendour as before, and was arrayed in the most beautiful robe, and enjoyed greater honours than his brother who had not fallen. For “these many years,” saith he “do I serve thee, neither transgressed I thy commandment at any time, and yet thou never gavest me a kid, that I might make merry with my friends; but when this thy son is come who hath devoured thy living with harlots, thou hast killed for him the fatted calf.” So great is the power of repentance.
