not the violator of the tombs carry on all his trade in the night? What then? Does it not overtake them as a thief? Does it not come upon them also uncertainly, but do they know it beforehand? How then does he say, “Ye have no need that aught be written unto you”? He speaks here not with respect to the uncertainty, but with respect to the calamity, that is, it will not come as an evil to them. For it will come uncertainly indeed even to them, but it will involve them in no trouble. “That that Day,” he says, “may not overtake you as a thief.” For in the case of those who are watching and who are in the light, if there should be any entry of a robber, it can do them no harm: so also it is with those who live well. But those who are sleeping he will strip of everything, and go off; that is, those who are trusting in the things of this life. Ver. 5. “For ye are all,” he says, “sons of light, and sons of the day.” And how is it possible to be “sons of the day”? Just as it is said, “sons of destruction” and “sons of hell.” Wherefore Christ also said to the Pharisees, “Woe unto you—for ye compass sea and land to make one proselyte, and when he is become so, ye make him a son of hell.” (Matt. xxiii. 15.) And again Paul said, “For which things’ sake cometh the wrath of God upon the sons of disobedience.” (Col. iii. 6.) That is, those who do the works of hell and the works of disobedience. So also sons of God are those who do things pleasing to God; so also sons of day and sons of light, those who do the works of light. “And we are not of the night nor of darkness.” Ver. 6, 7, 8. “So then let us not sleep, as do also the rest, but let us watch and be sober. For they that sleep sleep in the night; and they that be drunken are drunken in the night. But let us, since we are of the day, be sober.” Here he shows, that to be in the day depends on ourselves. For here indeed, in the case of the present day and night, it does not depend on ourselves. But night comes even against our will, and sleep overtakes us when we do not wish it. But with respect to that night and that sleep, it is not so, but it is in our power always to have it day, it is in our power always to watch. For to shut the eyes of the soul, and to bring on the sleep of wickedness, is not of nature, but of our own choice. “But let us watch,” he says, “and be sober.” For it is possible to sleep while awake, by doing nothing good. Wherefore he has added, “and be sober.” For even by day, if any one watches, but is not sober, he will fall into numberless dangers, so that sobriety is the intensity of watchfulness. “They that sleep,” he says, “sleep in the night, and they that be drunken are drunken in the night.” The drunkenness he here speaks of is not that from wine only, but that also which comes of all vices. For riches and the desire of wealth is a drunkenness of the soul, and so carnal lust; and every sin you can name is a 363 drunkenness of the soul. On what account then has he called vice sleep? Because in the first place the vicious man is inactive with respect to virtue: again, because he sees everything as a vision, he views nothing in its true light, but is full of dreams, and oftentimes of unreason- 640 1 Thessalonians 5:1,2
