Romans 6:12-14

Let not sin Any sinful disposition or inclination; therefore Since you are regenerate and spiritually alive; reign in your mortal body That is, reign in your soul while it dwells in your body. Many of our sinful inclinations have their seat in the body, and such evil inclinations as are of a more spiritual nature, are always some way more or less turned toward the body. That ye should obey it Should yield to and be overcome by it; in the lusts thereof In the irregular or inordinate desires which it excites within you. Neither yield ye your members The members of your bodies, or the faculties of your minds; the word μελη, here used, as also chapter Romans 7:5, signifying both, and indeed every thing in us and belonging to us, which is employed as an instrument in performing the works of the flesh, enumerated Galatians 5:19. For some of these do not require the members of the body to their being performed, but are wholly confined in their operation to the mind. Hence, Colossians 3:5, evil desire and covetousness are mentioned among our members upon the earth which we are to mortify. As instruments of unrighteousness Employed in its service; unto sin For the committing of it. The original word οπλα, rendered instruments, properly denotes military weapons; and may be here used to signify, that those who employ their powers, whether of body or mind, or any ability they possess, in the service of sin, do in fact fight for it, and for its master and father, Satan; and the principalities and powers under his command, against God and Christ, and all the company of heaven. But yield yourselves unto God Your lawful king, governor, and captain: dedicate yourselves, both body and soul, to his service; as those that are alive from the dead Who, after having been spiritually dead, are quickened and put in possession of spiritual life; that is, are no longer alienated from the life of God, but have vital union with God; not as formerly, carnally minded, which is death, but spiritually minded, which is life and peace, chap. Romans 8:6; no longer under condemnation to the second death, but justified and entitled to eternal life; and your members All your powers and abilities; as instruments of righteousness Instruments employed in the promotion of piety and virtue; unto God For his service and to his glory; or as weapons, to fight his battles, and oppose the designs of your spiritual enemies. For sin shall not have dominion over you It has no right, and shall not have power to reign over you. The word κυριευσει, denotes the government of a master over his slave, and might be rendered, shall not lord it over you. As if he had said, Though it is true sin is strong, and you are weak in yourselves, yet if you faithfully strive against it, looking to God for power from on high, you shall be enabled to conquer. For ye are not under the law Under a dispensation of terror and bondage, which only shows you your duty, but gives you no power to perform it; and which condemns you for your past violations of it, but offers no pardon to any on their repentance. The Mosaic law seems to be particularly intended, and the propriety of what is here observed is well illustrated, in that view, by the apostle in the next chapter. But his words may well imply also, that we are not so under any law as to be utterly condemned for want of a perfect conformity, or unsinning obedience to it. Not under a dispensation that requires such an obedience, under the penalty of death; which offers no assistance for enabling those who are under it to perform its requisitions, and grants no pardon to any sinner on his repentance. For the apprehension of being under such a dispensation would tend utterly to discourage us in all our attempts to conquer sin, and free ourselves from its power. But under grace Under the merciful dispensation of the gospel, which offers to all that will accept it, in the way of repentance toward God and faith in Christ, a free and full pardon for all that is past, an entire change of nature, and those continual supplies of grace, which strengthen human weakness, and confer both the will and the power to conquer every besetting sin, and live in the practice of universal holiness and righteousness. For the nature of the grace, that is, of the new gracious covenant, under which we are placed, is such, that it does not require an impossible perfect obedience to the law of Moses, or any law, but the obedience of faith; promising, at the same time, the aids of the Holy Spirit, to enable men to do God's will sincerely as far as they know it, and offering the pardon of sin to all on condition of repentance and faith in Christ, and in the declarations and promises of the gospel through him. Now under this gracious covenant mankind have been placed ever since the fall; ever since God said, The seed of the woman shall bruise the serpent's head; ever since that time the apostle's doctrine here, Ye are not under the law, but under grace, has been true of all the posterity of Adam; a doctrine which, instead of weakening the obligation of the law of God, written on men's hearts, or the moral law in any of its requirements, establishes it in the most effectual manner.
