Romans 8:13

I have quoted this passage so that I might make use of the apostle's words to deter your free will from evil and to exhort it to what is good. Nor should you on this account glory in man, i.e., in yourselves and not in the Lord. You are not living according to the flesh but are putting the deeds of the flesh to death by the Spirit.

"But if by the Spirit you mortify the deeds of the flesh, you shall live." And of this it has already been said above, how the body indeed ought to be dead because of sins, but the spirit is life because of justification. He, therefore, who acting according to the spirit mortifies the deeds of the flesh, shall live because of the spirit of life dwelling within him. Now one mortifies the deeds of the flesh in this manner. Charity is a fruit of the Spirit; hatred is a deed of the flesh: hatred, therefore, is mortified and extinguished through charity. Joy likewise is a fruit of the spirit, but the sorrow of this world, which works death, is a deed of the flesh: this, then, is extinguished if the joy of the spirit be in us. Peace is a fruit of the spirit; dissension and discord is a deed of the flesh; but it is certain that discord can be mortified through peace. So too the patience of the spirit extinguishes the impatience of the flesh, and goodness destroys malice, and meekness ferocity, and continence intemperance, and chastity slays unchastity; and in such an order he who through the spirit has mortified the deeds of the flesh shall live. It must indeed be observed that, just as he speaks not of that common death but of the death of sin — "For if you live according to the flesh, you shall die" — so also he speaks not of this common life but of that eternal life, to which everyone will come who, according to the things we have set forth above, has perfectly mortified by the spirit the deeds of the flesh. But this too we ought to know, that this mortification of the deeds of the flesh comes about through patience, and not suddenly, but little by little. […]

Paul does not say that we should mortify the flesh but "the deeds of the flesh," that is, the wisdom of the flesh, the attacks of the passions. For we have the grace of the Spirit to help us. Eternal life is the fruit of …

After showing how great the reward of a spiritual life is, and that it maketh Christ to dwell in us, and that it quickeneth our mortal bodies, and wingeth them to heaven, and rendereth the way of virtue easier, he next fitly introduces an exhortation to this purpose. "Therefore" we ought "not to live after the flesh." But this is not what he says, for he words it in a much more striking and powerful way, thus, "we are debtors to the Spirit." For saying, "we are debtors not to the flesh," indicates this. And this is a point he is everywhere giving proof of, that what God hath done for us is not matter of debt, but of mere grace. But after this, what we do is no longer matter of free-will offering, but of debt. For when he saith, "Ye are bought with a price, be not ye the servants of men"; and when he writes, "Ye are not your own"; and again in another passage he calls these selfsame things to their mind, in these words, "If One died for all, then all died that they should not henceforth live unto themselves." And it is to establish this that he says here also, "We are debtors;" then since he said we are "not" debtors "to the flesh," lest you should again take him to be speaking against the nature of the flesh, he does not leave speaking, but proceeds, "to live after the flesh." For there are many things which we do owe it, as giving it food, warmth, and rest, medicine when out of health, clothing, and a thousand other attentions. To prevent your supposing then that it is this ministration he is for abrogating when he says, "We are not debtors to the flesh," he explains it by saying, "to live after the flesh." For the care that I am for abrogating is, he means, that which leadeth to sin, as I should be for its having what is healing to it. You see that it is not the essence of the body whereof we are discoursing, but the deeds of the flesh. […]

By death he means here not only the immortal punishment in gehenna; but he also calls death the life spent on earth in evil deeds. On the contrary, if by spiritual life we put to death the evil deeds of the flesh, we shall live …

Then when he says, "for if you live according to the flesh," he gives the reason for the above conclusion. And first, as to the flesh, saying, "if you live according to the flesh," namely, by following the desires of the flesh, "you will die," …

The deeds of the flesh - Not only evil actions, but evil desires, tempers, thoughts. If ye mortify - Kill, destroy these. Ye shall live - The life of faith more abundantly here, and hereafter the life of glory.

We are not debtors to it; the flesh never did us so much kindness as to oblige us to serve it. It is implied that we are debtors to Christ and to the Spirit: there we owe our all, all we have and all we can do, by a thousand bonds and obligations.

For if ye live after the flesh, ye shall die,.... Such persons are dead, whilst they live, and shall die a second or an eternal death, if grace prevent not.

Note, (1) "There can be no safety, no holiness, no happiness, to those who are out of Christ: No "safety," because all such are under the condemnation of the law (Ro 8:1); no holiness, because such only as are united to Christ have the spirit of Christ (Ro 8:9); no happiness, because to be "carnally minded is death" (Ro 8:6)" [HODGE].

For if ye live after the flesh, ye shall die - Though μελλετε αποθνησκειν may mean, ye shall afterwards die, and this seems to indicate a temporal death, yet not exclusively of an eternal death; for both, and especially the latter, are necessarily implied. But if ye through the Spirit - If ye seek that grace and spiritual help which the Gospel of Christ furnishes, resist, and, by resisting, mortify the deeds of the flesh, against which the law gave you no assistance, ye shall live a life of faith, love, and holy obedience here, and a life of glory hereafter.
