16. But God wanted not power to make man such as that he should not be able to sin: but He chose rather to make him such, as that it should lie in his power to sin, if he would; not to sin, if he would not; forbidding the one, enjoining the other; that it might be to him first a good desert not to sin, and after a just reward not to be able to sin. For such also at the last will He makes His Saints, as to be without all power to sin. Such forsooth even now hath He His angels, whom in Him we so love, as to have no fear for any of them, lest by sinning he become a devil. And this we presume not of any just man in this mortal life. But we trust that all will be such in that immortal life. For Almighty God Who worketh good even of our evils, what good will He give, when He shall have set us free from all evils? Much may be said more fully and more subtilely on the good use of evil; but this is not what we have undertaken in our present discourse, and we must avoid in it excess of length.
Cui adjaceret c17. Now therefore let us return to that, wherefore we have said what we have. We have need of Continence, and we know it to be a divine gift, that our heart fall not away unto evil words, to make excuses in sins. But what sin is there but that we have need of Continence, to restrain it from being committed, since it is this very Continence which, in case it have been committed, restrains it from being defended by wicked pride? Universally therefore we have need of Continence, in order to turn away from evil. But to do good seems to pertain to another virtue, that is, to righteousness. This the sacred Psalm admonishes us, where we read, |Turn away from evil, and do good.| But with what end we do this, it adds bye and bye, saying, |Seek peace, and ensue it.| For we shall then have perfect peace, when, our nature cleaving inseparably to its Creator, we shall have nothing of ourselves opposed to ourselves. This our Saviour also Himself would have us to understand, so far as seems to me when He said, |Let your loins be girt, and your lamps burning.| What is it, to gird the loins? To restrain lusts, which is the work of continence. But to have lamps burning is to shine and glow with good works, which is the work of righteousness. Nor was He here silent with what end we do these things, adding and saying, |And you like unto men waiting for their Lord, when He cometh from the marriage.| But, when He shall have come, He will reward us, who have kept ourselves from those things which lust, and have done those things which charity hath bidden us: that we may reign in His perfect and eternal peace, without any strife of evil, and with the highest delight of good.
