1. Thessalonicher 5:6

others--Greek, "the rest" of the world: the unconverted (Th1 4:13). "Sleep" here is worldly apathy to spiritual things (Rom 13:11; Eph 5:14); in Th1 5:7, ordinary sleep; in Th1 5:10, death. watch--for Christ's coming; literally, "be wakeful." The same Greek occurs in Co1 15:34; Ti2 2:26. be sober--refraining from carnal indulgence, mental or sensual (Pe1 5:8).

On what had been said, the apostle grounds seasonable exhortations to several needful duties. I. To watchfulness and sobriety, Th1 5:6. These duties are distinct, yet they mutually befriend one another. For, while we are compassed about with so many temptations to intemperance and excess, we shall not keep sober, unless we be upon our guard, and, unless we keep sober, we shall not long watch. 1. Then let us not sleep as do others, but let us watch; we must not be secure and careless, nor indulge spiritual sloth and idleness. We must not be off our watch, but continually upon our guard against sin, and temptation to it. The generality of men are too careless of their duty and regardless of their spiritual enemies.

Either they do not consider the things of another world at all, because they are asleep; or they do not consider them aright, because they dream. But let us watch, and act like men that are awake, and that stand upon their guard. 2. Let us also be sober, or temperate and moderate. Let us keep our natural desires and appetites after the things of this world within due bounds. Sobriety is usually opposed to excess in meats and drinks, and here particularly it is opposed to drunkenness; but it also extends to all other temporal things. Thus our Saviour warned his disciples to take heed lest their hearts should be overcharged with surfeiting and drunkenness, and cares of this life, and so that day come on them unawares, Luk 21:34. Our moderation then, as to all temporal things, should be known to all men, because the Lord…

5:6 Stay alert and be clearheaded echoes Jesus’ call to be morally prepared because the disciples will not know the day of his return (Matt 24:42, 44; 25:13; cp. 1 Pet 1:13).
