That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.

That the justification of the law might be fulfilled in us, who walk not according to the flesh, but according to the spirit.

in order that the righteous requirement of the law should be fulfilled in us, who do not walk according to flesh but according to Spirit.

in order that in our case the requirements of the Law might be fully met. For our lives are regulated not by our earthly, but by our spiritual natures.

So that what was ordered by the law might be done in us, who are living, not in the way of the flesh, but in the way of the Spirit.

so that the justification of the law might be fulfilled in us. For we are not walking according to the flesh, but according to the spirit.

so that the requirements of the Law might be satisfied in us who live now in obedience, not to our earthly nature, but to the Spirit.

Ut justificatio Legis impleretur in nobis qui non secumdum carnem ambulamus, sed secundum Spiritum.

That the justification of the law might be fulfilled, etc. They who understand that the renewed, by the Spirit of Christ, fulfil the law, introduce a gloss wholly alien to the meaning of Paul; for the faithful, while they sojourn in this world, never make such a proficiency, as that the justification of the law becomes in them full or complete. This then must be applied to forgiveness; for when the obedience of Christ is accepted for us, the law is satisfied, so that we are counted just. For the perfection which the law demands was exhibited in our flesh, and for this reason -- that its rigor should no longer have the power to condemn us. But as Christ communicates his righteousness to none but to those whom he joins to himself by the bond of his Spirit, the work of renewal is again mentioned, lest Christ should be thought to be the minister of sin: for it is the inclination of many so to apply whatever is taught respecting the paternal kindness of God, as to encourage the lasciviousness of the flesh; and some malignantly slander this doctrine, as though it extinquished the desire to live uprightly.

Footnotes

1 - Commentators are divided as to the meaning of this verse. This and the second verse seem to bear a relation in sense to one another; so that if the second verse refers to justification, this also refers to it; but if freedom from the power of sin and death be what is taught in the former verse, the actual or personal fulfillment of the law must be what is intended here. Some, such as Pareus and Venema, consider justification to be the subject of both verses; and others, such as Scott and Doddridge, consider it to be sanctification. But Beza, Chalmers, as well as Calvin, somewhat inconsistently, regard the second verse as speaking of freedom from the power or dominion of sin, and not from its guilt or condemnation, and this verse as speaking of the imputed righteousness of Christ, and not of that righteousness which believers are enabled to perform by the Spirit's aid and influence. The verses seem so connected in the argument, that one of these two ideas must be held throughout. There is nothing decisive in the wording of this verse, though the cast of the expressions seem more favorable to the idea entertained by Doddridge and Scott, and especially what follows in the context, where the work of the Spirit is exclusively spoken of. The word dikaioma, is better rendered "righteousness" than "justification;" for "the righteousness to the law" means the righteousness which the law requires; and the words "might be fulfilled in us," may, with equal propriety as to the uses loquendi, be rendered, "might be performed by us." The verb pleroo has this meaning in Romans 13:8, and in other places. Viewed in this light the verse contains the same truth with what is expressed by "serving the law of God," in Romans 7:25, and the same with yielding our members as "instruments of righteousness unto God," in Romans 6:13. That this is to establish a justification by the law, is obviated by the consideration, that this righteousness is performed through the efficacy of Christ's death, and through the reviving power of the Spirit, and not through the law, and that it is not a justifying righteousness before God, for it is imperfect, and the law can acknowledge nothing as righteousness but what is perfect. The sanctification now begun will be finally completed; but it is all through grace: and the completion of this work will be a complete conformity with the immutable law of God. -- Ed.

That the righteousness of the law - That we might be conformed to the Law, or be obedient to its requirements, and no longer under the influence of the flesh and its corrupt desires.
Might be fulfilled - That we might be obedient, or comply with its demands.
Who walk - Note, Romans 8:1.

That the righteousness of the law might be fulfilled in us - That the guilt might be pardoned through the merit of that sacrifice; and that we might be enabled, by the power of his own grace and Spirit, to walk in newness of life; loving God with all our heart, soul, mind, and strength, and our neighbor as ourselves: and thus the righteousness, the spirit, design, and purpose of the law is fulfilled in us, through the strength of the Spirit of Christ, which is here put in opposition to the weakness of the law through the flesh.
It is very likely that the concluding clause of this verse, which is the very same as that found in the common text of the first verse, has been transferred to that verse from this place.

That the (l) righteousness of the law might be fulfilled (5) in us, who walk not after the flesh, but after the Spirit.
(l) The very substance of the law of God might be fulfilled, or that same which the law requires, that we may be found just before God: for if with our justification there is joined that sanctification which is imputed to us, we are just, according to the perfect form which the Lord requires. (5) He returns to that which he said, that the sanctification which is begun in us is a sure testimony of our ingrafting into Christ, which is a most plentiful fruit of a godly and honest life.

That the righteousness of the law might be fulfilled in us,.... By the righteousness of the law, is not meant the righteousness of the ceremonial law, though that was fulfilled by Christ; but of the moral law, which requires holiness of nature, righteousness of life, and death in case of disobedience; active righteousness, or obedience to the precepts of the law, is designed here. This is what the law requires; obedience to the commands of it is properly righteousness; and by Christ's obedience to it we are made righteous, and this gives the title to eternal life: now this is said to be "fulfilled in us"; this is not fulfilled by us in our own persons, nor can it be; could it, where would be the weakness of the law? man might then be justified by it, and so the grace of God, and the righteousness of Christ, must be set aside: there never was any mere man that could fulfil it; for obedience to it must not only be performed perfectly, but with intenseness of mind and spirit; a man must be sinless in thought, word, and deed; and this would be to put man upon a level with Adam in a state of innocence, and the angels in heaven: nor is this to be understood of any righteousness inherent in man; internal holiness is never called the righteousness of the law; and could it be thought to be righteousness, yet it can never be reckoned the whole righteousness of the law: and though it is a fruit of Christ's death, it is the work of the Spirit, and is neither the whole, nor any part of our justification: but this is to be understood of the righteousness of the law fulfilled by Christ, and imputed to us; Christ has fulfilled the whole righteousness of the law, all the requirements of it; this he has done in the room and stead of his people; and is imputed to them, by virtue of a federal union between him and them, he being the head, and they his members; and the law being fulfilled by him, it is reckoned all one as it was fulfilled in, or if by them; and hence they are personally, perfectly, and legally justified; and this is the end of Christ's being sent, of sin being laid on him, and condemned in him. The descriptive character of the persons, who appear to be interested in this blessing, is the same with that in Romans 8:1,
who walk not after the flesh, but after the Spirit: See Gill on Romans 8:1.

That the righteousness of the law--"the righteous demand," "the requirement" [ALFORD], Or "the precept" of the law; for it is not precisely the word so often used in this Epistle to denote "the righteousness which justifies" (Romans 1:17; Romans 3:21; Romans 4:5-6; Romans 5:17-18, Romans 5:21), but another form of the same word, intended to express the enactment of the law, meaning here, we believe, the practical obedience which the law calls for.
might be fulfilled in us--or, as we say, "realized in us."
who walk--the most ancient expression of the bent of one's life, whether in the direction of good or of evil (Genesis 48:15; Psalm 1:1; Isaiah 2:5; Micah 4:5; Ephesians 4:17; 1-John 1:6-7).
not after--that is, according to the dictates of
the flesh, but after the spirit--From Romans 8:9 it would seem that what is more immediately intended by "the spirit" here is our own mind as renewed and actuated by the Holy Ghost.

That the righteousness of the law - The holiness it required, described, Romans 8:11. Might be fulfilled in us, who walk not after the flesh, but after the Spirit - Who are guided in all our thoughts, words, and actions, not by corrupt nature, but by the Spirit of God. From this place St. Paul describes primarily the state of believers, and that of unbelievers only to illustrate this.
