Let no man deceive you. There have always been ungodly dogs, [1] by whom the threatenings of the prophets were made the subject of merriment and ridicule. We find such characters in our own day. In all ages, indeed, Satan raises up sorcerers of this description, who endeavor by unholy scoffs to escape the Divine judgment, and who actually exercise a kind of fascination over consciences not sufficiently established in the fear of God. "This is a trivial fault. Fornication is viewed by God as a light matter. Under the law of grace God is not so cruel. He has not formed us so as to be our own executioners. The frailty of nature excuses us." These and similar expressions are often used by the scoffers. Paul, on the contrary, exclaims that we must guard against that sophistry by which consciences are ensnared to their ruin. For because of these things cometh the wrath of God. If we consider the present tense to be here used, agreeably to the Hebrew idiom, for the future, these words are a threatening of the last judgment. But I agree with those who take the word cometh in an indefinite sense, -- the word of God usually cometh, -- as reminding them of the ordinary judgments of God which were executed before their own eyes. And certainly, if we were not blind and slothful, there are sufficiently numerous examples by which God testifies that he is the just avenger of such crimes, -- examples of the pouring out of divine indignation, privately against individuals, and publicly against cities, and kings, and nations. Upon the children of disobedience, -- upon unbelievers or rebels. This expression must not be overlooked. Paul is now addressing believers, and his object is not so much to present alarming views of their own danger, as to rouse them to behold reflected in wicked men, as in mirrors, the dreadful judgments of God. God does not make himself an object of terror to his children, that they may avoid him, but does all that can be done in a fatherly manner, to draw them to himself. They ought to learn this lesson, not to involve themselves in a dangerous fellowship with the ungodly, whose ruin is thus foreseen.

Let no man deceive you - Let no one by artful pleas persuade you that; there will be no danger from practicing these vices, We may suppose that they would be under strong temptations to mingle in the "happy" and festive scenes where these vices were not frowned on, or where they were practiced; or that they might be tempted to commit them by some of the plausible arguments which were then used for their indulgence. Many of their friends may have been in these circles; and they would endeavor to convince them that such were the customs which had been long practiced, and that there could be no harm still in their indulgence. Not a few philosophers endeavored, as is well known, to defend some of these practices, and even practiced them themselves; see the notes on Romans. 1. It required, therefore, all the authority of an apostle to convince them, that however plausible were the arguments in defense of them, they certainly exposed those who practiced them to the wrath of God.
For because of these things cometh the wrath of God - see the notes on Romans 1:18; Romans 2:8-9, note.
Upon the children of disobedience - see the Matthew 1:1, note; Romans 2:8, note.

Let no man deceive you - Suffer no man to persuade you that any of these things are innocent, or that they are unavoidable frailties of human nature; they are all sins and abominations in the sight of God; those who practice them are children of disobedience; and on account of such practices the wrath of God - Divine punishment, must come upon them.

Let no man deceive you with vain words,.... With vain philosophy, vain babblings, with foolish and filthy talking; suggesting that these were not sinful the apostle had condemned; or that they were small sins, the frailties of human life; and that God would take no notice of them, and they might continue in them with impunity: such deceivers there were, doctrinal and practical ones, who lay in wait to deceive men with such vain pretences; and there was danger of being carried away with their error; for the heart is deceitful and desperately wicked, and is easily taken in such snares: wherefore the apostle cautions against such deceptions, adding,
for because of these things; fornication, uncleanness, covetousness, filthiness, foolish talking, and jesting:
the wrath of God cometh upon the children of disobedience; in temporal judgments, and in eternal ruin; there have been instances of it; it is usually the case, and always if grace prevents not; this wrath comes down from above, and sometimes suddenly, with great force and power, like a mighty flood; and there is no standing up under it, and against it; and though it falls upon the children of disobedience, such as are disobedient both to law and Gospel, are unbelievers in Christ, and not persuadable by his ministers, are stubborn, obstinate, and rebellious; yet it shows how much these things are displeasing to God, and resented by him, and therefore should be avoided by his people; and the consideration of their not being appointed to this wrath, though deserving of it as others, and of their deliverance from it by Christ, should engage them the more to abstain from these sins.

vain--empty, unreal words, namely, palliations of "uncleanness," Ephesians 5:3-4; Isaiah 5:20 (that it is natural to indulge in love), "covetousness" (that it is useful to society that men should pursue gain), and "jesting" (that it is witty and clever, and that God will not so severely punish for such things).
because of these things--uncleanness, covetousness, &c. (Ephesians 5:3-5).
cometh--present, not merely "shall come." Is as sure as if already come.
children--rather, "sons of disobedience" (Ephesians 2:2-3). The children of unbelief in doctrine (Deuteronomy 32:20) are "children of disobedience" in practice, and these again are "children of wrath."

Let no man deceive you with vain words. With artful pleas that sinful things are not sinful.
For. Because of just such sins as they excuse, God's wrath will be visited upon all who live in (the children of) disobedience.
Partakers. Have no share with them in their sins.

Because of these things - As innocent as the heathens esteem them, and as those dealers in vain words would persuade you to think them.
