5:3-14 Filthy lusts must be rooted out. These sins must be dreaded and detested. Here are not only cautions against gross acts of sin, but against what some may make light of. But these things are so far from being profitable. that they pollute and poison the hearers. Our cheerfulness should show itself as becomes Christians, in what may tend to God's glory. A covetous man makes a god of his money; places that hope, confidence, and delight, in worldly good, which should be in God only. Those who allow themselves, either in the lusts of the flesh or the love of the world, belong not to the kingdom of grace, nor shall they come to the kingdom of glory. When the vilest transgressors repent and believe the gospel, they become children of obedience, from whom God's wrath is turned away. Dare we make light of that which brings down the wrath of God? Sinners, like men in the dark, are going they know not whither, and doing they know not what. But the grace of God wrought a mighty change in the souls of many. Walk as children of light, as having knowledge and holiness. These works of darkness are unfruitful, whatever profit they may boast; for they end in the destruction of the impenitent sinner. There are many ways of abetting, or taking part in the sins of others; by commendation, counsel, consent, or concealment. And if we share with others in their sins, we must expect to share in their plagues. If we do not reprove the sins of others, we have fellowship with them. A good man will be ashamed to speak of what many wicked men are not ashamed to do. We must have not only a sight and a knowledge that sin is sin, and in some measure shameful, but see it as a breach of God's holy law. After the example of prophets and apostles, we should call on those asleep and dead in sin, to awake and arise, that Christ may give them light.
11. unfruitful works of darkness—Sins are terminated in themselves, and therefore are called "works," not "fruits" (Ga 5:19, 22). Their only fruit is that which is not in a true sense fruit (De 32:32), namely, "death" (Ro 6:21; Ga 6:8). Plants cannot bear "fruit" in the absence of light. Sin is "darkness," and its parent is the prince of darkness (Eph 6:12). Graces, on the other hand, as flourishing in "the light," are reproductive, and abound in fruits; which, as harmoniously combining in one whole, are termed (in the singular) "the FRUIT of the Spirit" (Eph 5:9).
rather, &c.—Translate as Greek, "rather even reprove them" (compare Mt 5:14-16). Not only "have no fellowship, but even reprove them," namely, in words, and in your deeds, which, shining with "the light," virtually reprove all that is contrary to light (Eph 5:13; Joh 3:19-21). "Have no fellowship," does not imply that we can avoid all intercourse (1Co 5:10), but "avoid such fellowship as will defile yourselves"; just as light, though it touch filth, is not soiled by it; nay, as light detects it, so, "even reprove sin."
