1 Thessalonians 5:7

"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." 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. 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 drunkenness of the soul.
