(12-14) Practical and hortatory consequence. Therefore expel sin, and refuse to obey its evil promptings. Keep your bodies pure and clean. Let them no longer be weapons in the hands of wickedness; let them rather be weapons with which to fight the battle of righteousness and of God. You have every encouragement to do this. For sin shall no longer play the tyrant over you. The stern and gloomy Empire of Law (which only served to heighten the guilt of sin) is over, and in its stead the only power to which you are subject is that of free forgiveness.

(12) Mortal.--And therefore at variance with the immortal life just described.

Verse 12. - Let not sin therefore reign in your mortal body, that ye should obey the lusts thereof. (The reading of the Textus Receptus, "obey it in the lusts thereof," has but weak support.) Though our "old man" is conceived of as crucified with Christ - though this is theoretically and potentially our position - yet our actual lives may be at variance with it; for we are still in our present "mortal body," with its lusts remaining; and sin is still a power, not yet destroyed, which may, if we let it, have domination over us still. Regeneration is not regarded as having changed our nature, or eradicated all our evil propensions, but as having introduced into us a higher power - "the power of his resurrection" (Philippians 3:10) - in virtue of which we may resist the attempted domination of sin. But it still rests with us whether we will give our allegiance to sin or to Christ. Οὐ γὰρ τὴν φύσιν η΅λθεν ἀνελεῖν ἀλλὰ τὴν προαίρεσιν διορθῶσαι (Chrysostom). The lusts, obedience to which is equivalent to letting sin reign, are said to be those of our "mortal body," because it is in our present bodily organization that the lusts tempting us to evil rise. But it is not in their soliciting us, but in the will assenting to them, that the sin lies. "Quia non consentimus desideriis pravis in gratia sumus" (Augustine, 'Prop.,' 35). "Cupiditates corporis sunt fomes, peccatum ignis" (Bengel). The epithet θνητῷ ("mortal") is fitly used as distinguishing our present perishable framework - the earthen vessels in which we have our treasure (2 Corinthians 4:7) - from our real inward personality, ἔσωθεν ἄνθρωπος (2 Corinthians 4:16), which is regarded as having risen with Christ, so as to live to God for ever. "Vos enim, viventes, abalienati estis a corpore vestro (cf. Romans 8:10)" (Bengel).

6:11-15 The strongest motives against sin, and to enforce holiness, are here stated. Being made free from the reign of sin, alive unto God, and having the prospect of eternal life, it becomes believers to be greatly concerned to advance thereto. But, as unholy lusts are not quite rooted out in this life, it must be the care of the Christian to resist their motions, earnestly striving, that, through Divine grace, they may not prevail in this mortal state. Let the thought that this state will soon be at an end, encourage the true Christian, as to the motions of lusts, which so often perplex and distress him. Let us present all our powers to God, as weapons or tools ready for the warfare, and work of righteousness, in his service. There is strength in the covenant of grace for us. Sin shall not have dominion. God's promises to us are more powerful and effectual for mortifying sin, than our promises to God. Sin may struggle in a real believer, and create him a great deal of trouble, but it shall not have dominion; it may vex him, but it shall not rule over him. Shall any take occasion from this encouraging doctrine to allow themselves in the practice of any sin? Far be such abominable thoughts, so contrary to the perfections of God, and the design of his gospel, so opposed to being under grace. What can be a stronger motive against sin than the love of Christ? Shall we sin against so much goodness, and such love?Let not sin therefore reign in your mortal body,.... Since grace reigns in you, sin should not: seeing ye are dead to sin, are baptized into the death of Christ, and are dead with him, and alive through him, sin therefore should not reign in you, and over you. This exhortation does not suppose a freewill power in man naturally, for this is spoken to persons, who had the Spirit and grace of Christ, and in whom God had wrought both to will and to do of his good pleasure; nor is this exhortation unnecessary to believers, though they are dead to sin, and though God has promised it shall not have the dominion over them, and though reigning sin, as divines say, cannot be in regenerate persons; for though they are entirely dead to sin as justified persons, yet not perfectly so as sanctified: they are indeed dead to sin, but sin is not dead in them; it struggles, it makes war, leads captive, and threatens absolute and universal dominion, wherefore such an exhortation is necessary; besides, though God has promised that sin shall not have the dominion, yet making use of means, such as prayer to God that it may not, striving against it, opposing it, in order to hinder its dominion, are no ways inconsistent with the promise of God, whose promises often have their accomplishment in the use of means: moreover, whereas some divines say, that reigning sin may be and others that it cannot be in regenerate persons, it should be observed, that if by reigning sin is meant, sinning against God out of malice and contempt, with the whole heart, without any struggle against it, or repentance for it, or so as to lose the grace of God, and never rise more, then it must be said that it cannot be in a regenerate man; but if by it is meant, falling into sin against their consciences, knowingly and willingly, so as to distress their minds, lose their peace, and grieve the Spirit of God, so as to be held under it, and be led captive by it, such power sin may have in them, and over them; and therefore the exhortation is not needless; and when the apostle says, let it not reign "in your mortal body", by it is either meant the whole man, or rather the body only, which is the instrument of sinning, and is become mortal through sin; and being so, is a reason why it should not reign in it, since it has done so much mischief to it already: and this also denotes the time of sin's being in us, and of the danger of its reigning in us; it is only whilst we are in this mortal body; and the consideration of our mortality should quicken us to war against sin, and be careful not to

obey it in the lusts thereof; the lusts of the body, or flesh, which are therefore sometimes called fleshly lusts, are many, and have great power and influence; and may be said to be obeyed, when provision is made to fulfil them, when these are the business of a man's life, and the whole of his conversation is taken up in them, without struggle against them, or opposition to them; and heroin lies the reign of sin.
