“"For the law," says he, "of the Spirit of life in Christ Jesus hath made me free from the law of sin and death," -that, surely, which he previously mentioned as dwelling in our members. Our members, therefore, will no longer be subject to the law of death, because they cease to serve that of sin, from both which they have been set free.”

“On this text, those who find fault with the flesh, and contend it was no part of God's creation, attack us. What are we to say then? Just what we did before, when discussing the Law: that as there he makes sin answerable for everything so here also. For he does not say, that the flesh worketh it, but just the contrary, "it is not I that do it, but sin that dwelleth in me." But if he does say that "there dwelleth no good thing in it," still this is no charge against the flesh. For the fact that "no good thing dwelleth in it," does not show that it is evil itself. Now we admit, that the flesh is not so great as the soul, and is inferior to it, yet not contrary, or opposed to it, or evil; but that it is beneath the soul, as a harp beneath a harper, and as a ship under the pilot. And these are not contrary to those who guide and use them, but go with them entirely, yet are not of the same honor with the artist. As then a person who says, that the art resides not in the harp or the ship, but in the pilot or harper, is not finding fault with the instruments, but pointing out the great difference between them and the artist; so Paul in saying, that "in my flesh dwelleth no good thing," is not finding fault with the body, but pointing out the soul's superiority. For this it is that has the whole duty of pilotage put into its hands, and that of playing. And this Paul here points out, giving the governing power to the soul, and after dividing man into these two things, the soul and the body, he says, that the flesh has less of reason, and is destitute of discretion, and ranks among things to be led, not among things that lead. But the soul has more wisdom, and can see what is to be done and what not, yet is not equal to pulling in the horse as it wishes. And this would be a charge not against the flesh only, but against the soul also, which knows indeed what it ought to do, but still does not carry out in practice what seems best to it. "For to will," he says, "is present with me; but how to perform that which is good, I find not." Here again in the words, "I find not," he does not speak of any ignorance or perplexity, but a kind of thwarting and crafty assault made by sin, which he therefore points more clearly out in the next words.”

“After the Apostle has shown that the law is good from the fact that it agrees with reason, here he draws two conclusions according to the two things he had set down; the second is set down where he says, "But I see another law," etc. Concerning the first he does two things. First he draws the conclusion from what has been said; second he sets down a sign for the greater manifestation of it, where he says, "I am delighted," etc. Now he had set down two things above. The first indeed, that the law is spiritual; this having now been proved, he concludes thus: "I find then" — that is, by experience — that the law of Moses is in accord with me willing to do good, that is, with my reason, by which I approve the good and detest the evil, since that law itself also commands the good and forbids the evil. Deuteronomy 30:14: "The word is very near to you, in your mouth and in your heart, that you may do it." And in this way it was necessary that — that is, because evil, that is, sin or the tinder of sin, is present to me — that is, lies alongside my reason, as it were inhabiting my flesh. Micah 8:5: "From her that sleeps in your bosom, guard the closures of your mouth," that is, from the flesh. Then when he says, "For I am delighted," etc., he sets down a sign by which it is shown that the law agrees with reason. For no one is delighted except in that which is fitting to him. But man according to reason is delighted in the law of God; therefore the law of God is fitting to reason. And this is what he says: "I am delighted with the law of God according to the interior man," that is, according to reason and mind, which is called the interior man — not because the soul is figured according to the form of a man, as Tertullian held, or because it alone is the man, as Plato held, that man is a soul using a body; but because that which is more principal in man is called man, as was said above. Now in man that which is more principal according to appearance indeed is that which is exterior, namely the body so figured, which is called the exterior man; but according to truth, that which is intrinsic, namely the mind or reason, is what is here called the interior man. Psalm 118:103: "How sweet are your words to my throat." 1 Maccabees 12:9: "Having for our solace the holy books that are in our hands." Then when he says, "But I see," etc., he sets down another conclusion which corresponds to what he had said above, saying, "But I am carnal," etc. Saying, "I see another law in my members," which is the tinder of sin, which indeed can be called law for a twofold reason. In one way on account of similar effects, because just as the law induces to doing good, so the tinder induces to sinning. In another way by comparison to its cause. Now since the tinder is a certain punishment of sin, it has a twofold cause: one indeed sin itself, which took dominion in the sinner and imposed on him a law, which is the tinder, just as a lord imposes a law on a conquered servant. The other cause of the tinder is God, who placed this punishment on man when he sinned, so that the lower powers should not obey his reason. And according to this, the very disobedience of the lower powers, which is called the tinder, is called law insofar as it is introduced through the law of divine justice, like the sentence of a just judge, which has the force of law, according to that saying, 1 Kings 30:25: "And this was done from that day forward, and it was appointed and determined, and became as it were a law in Israel unto this day." But this law consists originally indeed in the sensitive appetite, but is found diffusively in all the members, which serve concupiscence unto sinning. Above, Romans 6:19: "Just as you presented your members to serve uncleanness," etc. And therefore he says, "in my members." Now this law has two effects in man. For first it resists reason, and as to this he says, "fighting against the law of my mind," that is, against the law of Moses, which is called the law of the mind insofar as it accords with the mind, or against the natural law, which is called the law of the mind because it is naturally implanted in the mind. Above, Romans 2:15: "Who show the work of the law written in their hearts." And concerning this fighting it is said, Galatians 5:17: "The flesh lusts against the spirit." The second effect is that it reduces man into servitude. And as to this he adds, "and captivating me," or according to another reading, "leading me captive," "in the law of sin, which is in my members," that is, in myself, after the manner of Hebrew speech, according to which nouns are put in place of pronouns. But the law of sin takes man captive in two ways: in one way, the sinning man, through consent and operation; in another way, the man established under grace, as to the movement of concupiscence. Concerning this captivity it is said in Psalm 125:1: "When the Lord turned the captivity of Sion." Then when he says, "Unhappy man that I am," etc., he deals with liberation from the law of sin, and does three things concerning this. First indeed he poses the question; second he gives the answer, where he says, "the grace of God," etc.; third he draws the conclusion, where he says, "therefore I myself," etc. Concerning the first he does two things. One thing indeed he confesses, namely his own misery, when he says, "Unhappy man that I am" — which indeed is on account of the sin which dwells in man, whether only as to the flesh, as in the just man, or also as to the mind, as in the sinner. Proverbs 14:34: "Sin makes peoples miserable." Psalm 37:7: "I have been made miserable and bowed down even to the end." The other thing he asks, saying, "Who will deliver me from the body of this death?" This indeed seems to be the question of one desiring, according to that saying, Psalm 141:10: "Bring my soul out of prison." It must be known, however, that in the body of man one can consider both the very nature of the body, which is fitting to the soul, whence the soul does not wish to be separated from it — 2 Corinthians 5:4: "We do not wish to be stripped, but to be clothed over" — and again the corruption of the body, which weighs down the soul, according to that saying, Wisdom 9:15: "The body which is corrupted weighs down the soul," etc. And therefore he says pointedly, "from the body of this death." Then when he says, "The grace of God," etc., he answers the question. For man cannot by his own powers be freed from the corruption of the body, nor even of the soul, although he consents with reason against sin, but only through the grace of Christ, according to that saying, John 8:36: "If the Son shall have made you free, you shall be free indeed." And therefore there follows, "the grace of God" — namely, will free me — "which is given through Jesus Christ." John 1:17: "Grace and truth came through Jesus Christ." Now this frees from the body of this death in two ways: in one way, so that the corruption of the body does not dominate the mind, dragging it to sin; in another way, so that the corruption of the body is totally removed. As to the first, therefore, it is fitting for the sinner to say: "grace has freed me from the body of this death," that is, it has freed me from the sin into which the soul is led by the corruption of the body. But from this the just man is already freed, whence it belongs to him to say, as to the second: "the grace of God has freed me from the body of this death," namely, that in my body there be no corruption of sin or of death — which will be in the resurrection. Then when he says, "Therefore I myself," etc., he draws a conclusion which, according to the two aforesaid expositions, is inferred differently from what precedes. For according as the aforesaid words are expounded in the person of the sinner, the conclusion is to be inferred thus: it was said that the grace of God freed me from the body of this death, namely so that I might not be led by it into sin; therefore, when I shall already be freed, with the mind I serve the law of God, but according to the flesh the law of sin, which indeed remains in the flesh as to the tinder, through which the flesh lusts against the spirit. But if the aforesaid words are understood from the person of the just man, it is to be inferred thus: the grace of God through Jesus Christ freed me from the body of this death, namely so that in me there be no corruption of sin and of death. Therefore, I myself, one and the same, before I am freed, with the mind serve the law of God, consenting to it, but with the flesh I serve the law of sin, insofar as my flesh, according to the law of the flesh, is moved to concupiscence.”

“Now then, it is no more I that do it,.... This is another inference, deduced from what is before said, that since he did not approve, but hated what he did, and willed the contrary, it was not he as spiritual, as born again, as a new man, a new creature, that did it; see Jo1 3:9. He says, But sin that dwelleth in me; the old man, the carnal I, the evil present with him, the law in his members; which not only existed in him, and wrought in him, and that at times very strongly, but dwelt in him, had its abode in him, as it has in all regenerate persons, and will have, as long as they are in the body.”

“Now then it is no more I - It is not that I which constitutes reason and conscience, but sin-corrupt and sensual inclinations, that dwelleth in me - that has the entire domination over my reason, darkening my understanding, and perverting my judgment; for which there is condemnation in the law, but no cure. So we find here that there is a principle in the unregenerate man stronger than reason itself; a principle which is, properly speaking, not of the essence of the soul, but acts in it, as its lord, or as a tyrant. This is inbred and indwelling sin - the seed of the serpent; by which the whole soul is darkened, confused, perverted, and excited to rebellion against God.”

“Now then it is no more I that do it: To will good is present with me. These expressions all shew that he speaks of temptations that affect the sense only, the imagination, or the members of the body, but to which the mind and the will give no consent, but retain an aversion to them; and so long they never can be truly and properly sins, which must be with full deliberation and consent. (Witham) — The apostle here means to say, that he knew by experience that evil and not good dwelt within him, according to the flesh. He does not contradict this passage when he says elsewhere, that our members are the temples of the Holy Ghost: (1 Corinthians iii. 6.[16.?] &c.) for good cannot be found in our flesh, inasmuch as it is corrupted by sin; whence our Saviour says, “What is born of flesh, is flesh.” (John iii.) But good is in our body, when our members under the influence of the soul, renewed by the Holy Ghost residing in it, are employed in good works. The meaning of this passage is, that although now healed and renewed by grace, he could have a perfect desire of doing good; yet still on account of the evil of concupiscence dwelling in his flesh, he found not himself able to perform all the good he wished, because concupiscence was always urging him on to evil against his will.

“Now then it is no more I--my renewed self. that do it--"that work it." but sin which dwelleth in me--that principle of sin that still has its abode in me. To explain this and the following statements, as many do (even BENGEL and THOLUCK), of the sins of unrenewed men against their better convictions, is to do painful violence to the apostle's language, and to affirm of the unregenerate what is untrue. That coexistence and mutual hostility of "flesh" and "spirit" in the same renewed man, which is so clearly taught in Rom 8:4, &c., and in Gal 5:16, &c., is the true and only key to the language of this and the following verses. (It is hardly necessary to say that the apostle means not to disown the blame of yielding to his corruptions, by saying, "it is not he that does it, but sin that dwelleth in him." Early heretics thus abused his language; but the whole strain of the passage shows that his sole object in thus expressing himself was to bring more vividly before his readers the conflict of two opposite principles, and how entirely, as a new man--honoring from his inmost soul the law of God--he condemned and renounced his corrupt nature, with its affections and lusts, its stirrings and its outgoings, root and branch).”
