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?

14. For Sin shall not have dominion over you—as the slaves of a tyrant lord.

for ye are not under the law, but under grace—The force of this glorious assurance can only be felt by observing the grounds on which it rests. To be "under the law" is, first, to be under its claim to entire obedience; and so, next under its curse for the breach of these. And as all power to obey can reach the sinner only through Grace, of which the law knows nothing, it follows that to be "under the law" is, finally, to be shut up under an inability to keep it, and consequently to be the helpless slave of sin. On the other hand, to be "under grace," is to be under the glorious canopy and saving effects of that "grace which reigns through righteousness unto eternal life through Jesus Christ our Lord" (see on [2205]Ro 5:20, 21). The curse of the law has been completely lifted from off them; they are made "the righteousness of God in Him"; and they are "alive unto God through Jesus Christ." So that, as when they were "under the law," Sin could not but have dominion over them, so now that they are "under grace," Sin cannot but be subdued under them. If before, Sin resistlessly triumphed, Grace will now be more than conqueror.
