(6) Let us not sleep.--The metaphor here expresses not so much actual sin (Ephesians 5:14) as carelessness in spiritual and moral things. "Let us not say, 'Peace and safety,' and resign ourselves to indifference about Christ's coming." St. Paul (as always) indicates that it was possible for "children of light" to be converted back into "children of darkness."

Others.--Rather, the rest, as in 1Thessalonians 4:13 : so also Romans 11:7; Ephesians 2:3.

Watch and be sober.--The comparison of night now suggests to the writer another thought besides that of sloth, namely, that of dissipation. Christians are not to turn day into night by debauchery any more than by sleep.

Verse 6. - Therefore; because we are the children of the, light and of the day, because we have been enlightened and purified, we ought to be watchful and sober, so that we may not be unprepared for the day of the Lord. Privileges will avail us nothing, unless we use them and walk up to them. Let us not sleep. Sleep is here evidently used metaphorically to denote religious carelessness. As do others; the unbelieving and ungodly. But let us watch and be sober; evidently to be understood metaphorically of spiritual vigilance and sobriety: watchfulness denoting wakefulness from sleep, and sobriety freedom from intoxication. Both must be combined: we must be watchful, on our guard, and we must be sober, armed and prepared; "for even by day," observes St. Chrysostom, "if one watches, but is not sober, he will fall into numberless dangers." The same exhortation is given by Peter, but in the reverse order: "Be sober, be vigilant" (1 Peter 5:8).

5:6-11 Most of mankind do not consider the things of another world at all, because they are asleep; or they do not consider them aright, because they sleep and dream. Our moderation as to all earthly things should be known to all men. Shall Christians, who have the light of the blessed gospel shining in their faces, be careless about their souls, and unmindful of another world? We need the spiritual armour, or the three Christian graces, faith, love, and hope. Faith; if we believe that the eye of God is always upon us, that there is another world to prepare for, we shall see reason to watch and be sober. True and fervent love to God, and the things of God, will keep us watchful and sober. If we have hope of salvation, let us take heed of any thing that would shake our trust in the Lord. We have ground on which to build unshaken hope, when we consider, that salvation is by our Lord Jesus Christ, who died for us, to atone for our sins and to ransom our souls. We should join in prayer and praise one with another. We should set a good example one before another, and this is the best means to answer the end of society. Thus we shall learn how to live to Him, with whom we hope to live for ever.Therefore let us not sleep as do others.... As the rest of the Gentiles, as unconverted persons, who are in a state of darkness, and are children of the night; let us not act that part they do, or be like them; which professors of religion too much are, when they indulge themselves in carnal lusts and pleasures, and are careless and thoughtless about the coming of the day of the Lord; and get into a stupid, drowsy, and slumbering frame of spirit; when grace lies dormant as if it was not, and they grow backward to, and slothful in the discharge of duty, and content themselves with the bare externals of religion; and become lukewarm and indifferent with respect to the truths and ordinance of the Gospel, the cause of God, the interest of religion, and glory of Christ; and are unconcerned about sins of omission or commission: and are willing to continue in such a position, being displeased at every admonition and exhortation given them to awake; but this is very unbecoming children of the light, and of the day:

but let us watch; over ourselves, our hearts, thoughts, affections, words and actions; and over others, our fellow Christians, that they give not into bad principles and evil practices; and against sin, and all appearance of it; against the temptations of Satan, the snares of the world, and the errors of wicked men, who lie in wait to deceive; and in the word and ordinances, and particularly in prayer, both unto it, in it, and after it; and for the second coming of Christ, with faith, affection, and patience; and the rather, because of the uncertainty of the time of it;

and be sober; not only in body, abstaining from excessive eating and drinking, using this world, and the good things of it, so as not to abuse them, or ourselves with them; but also in mind, that the heart be overcharged with the cares of this world; for men may be inebriated with the world, as well as with wine; and the one is as prejudicial to the soul as the other is to the body; for an immoderate care for, and pursuit after the world, chokes the word, makes it unfruitful, and runs persons into divers snares and temptations, and hurtful lusts. The Arabic version renders it, "let us repent"; and the Ethiopic version, "let us understand"; as intending the sobriety of the mind, repentance being an after thought of the mind, a serious reflection on past actions with sorrow and concern; and thinking soberly, and not more highly than a man ought to think of himself, his gifts, his attainments and abilities, in opposition to pride, vanity, and self-conceit, is very becoming; and shows a true and well informed understanding and judgment, and that a man is really sober and himself.
