13. It is therefore by the sentence of God that he is abandoned who deserves to be so, while over some sinners God exercises forbearance; not, however, without a definite principle of action. Nay, the very fact that He is long-suffering conduces to the advantage of those very persons, since the soul over which He exercises this providential care is immortal; and, as being immortal and everlasting, it is not, although not immediately cared for, excluded from salvation, which is postponed to a more convenient time. For perhaps it is expedient for those who have been more deeply imbued with the poison of wickedness to obtain this salvation at a later period. For as medical men sometimes, although they could quickly cover over the scars of wounds, keep back and delay the cure for the present, in the expectation of a better and more perfect recovery, knowing that it is more salutary to retard the treatment in the cases of swellings caused by wounds, and to allow the malignant humours to flow off for a while, rather than to hasten a superficial cure, by shutting up in the veins the poison of a morbid humour, which, excluded from its customary outlets, will undoubtedly creep into the inner parts of the limbs, and penetrate to the very vitals of the viscera, producing no longer mere disease in the body, but causing destruction to life; so, in like manner, God also, who knows the secret things of the heart, and foreknows the future, in much forbearance allows certain events to happen, which, coming from without upon men, cause to come forth into the light the passions and vices which are concealed within, that by their means those may be cleansed and cured who, through great negligence and carelessness, have admitted within themselves the roots and seeds of sins, so that, when driven outwards and brought to the surface, they may in a certain degree be cast forth and dispersed. And thus, although a man may appear to be afflicted with evils of a serious kind, suffering convulsions in all his limbs, he may nevertheless, at some future time, obtain relief and a cessation from his trouble; and, after enduring his afflictions to satiety, may, after many sufferings, be restored again to his (proper) condition. For God deals with souls not merely with a view to the short space of our present life, included within sixty years or more, but with reference to a perpetual and never-ending period, exercising His providential care over souls that are immortal, even as He Himself is eternal and immortal. For He made the rational nature, which He formed in His own image and likeness, incorruptible; and therefore the soul, which is immortal, is not excluded by the shortness of the present life from the divine remedies and cures.
