(4) The consequence of this was a great change. Hitherto the Law could not be kept because of the antagonistic influence of the flesh; henceforth it may be kept for the reason that this influence has ceased and that its place is taken by the influence of the Spirit.
The righteousness.--The just requirement of the Law, its due and rightful claims.
Might be fulfilled in us.--That we might be examples of its fulfilment.
Who walk not after the flesh.--Who direct our conduct not as the flesh would guide us. but according to the dictates and guidance of the Spirit--i.e., the indwelling Spirit of Christ, as in Romans 8:2.
Verse 4. - That the ordinance (or, righteous requirement, rather than righteousness, as in the Authorized Version. The word is δίκαιωμα, not δικαιοσύνη. It Occurs elsewhere in the New Testament, Luke 1:6; Romans 1:32; Romans 2:26; Hebrews 9:1; and in a like sense often in the LXX.; also, though with a difference of meaning, Romans 5:16, 18) of the Law may be fulfilled in us, who walk not after the flesh, but after the Spirit. This, then, is the purpose of Christ's victory over sin - that the requirement of the Law in us too may be fulfilled; which evidently means more -than that his victory may be imputed to us, on the ground of our faith only, while we remain as we were. The expression, δὶκαιωμα πληρωθῆ, and also the condition appended at the end of the verse, imply that the "Spirit of life" must so dominate over the flesh in ourselves that the Law may forfeit its claims over us. The sinful propensions of the flesh remain in us still (as the verses that follow distinctly show); but the Spirit that is in us is strong enough to overcome them now (cf. Galatians 5:16-18). It does not follow from this that any Christians will actually avoid all sin, or that they can be accepted on theground of their own performance: to say this would be to contradict other Scripture (cf. James 2:10; 1 John 1:8); and Paul confessed himself to be not already perfected (Philippians 3:12). But perfection, through Christ who lives in them, is put before us as, at any rate, the aim of the regenerate (cf. Matthew 5:48); and by actual and progressive holiness they are to show that their union with Christ is real. His Spirit within them must, at any rate, give a new direction and tone to their characters and lives.
8:1-9 Believers may be chastened of the Lord, but will not be condemned with the world. By their union with Christ through faith, they are thus secured. What is the principle of their walk; the flesh or the Spirit, the old or the new nature, corruption or grace? For which of these do we make provision, by which are we governed? The unrenewed will is unable to keep any commandment fully. And the law, besides outward duties, requires inward obedience. God showed abhorrence of sin by the sufferings of his Son in the flesh, that the believer's person might be pardoned and justified. Thus satisfaction was made to Divine justice, and the way of salvation opened for the sinner. By the Spirit the law of love is written upon the heart, and though the righteousness of the law is not fulfilled by us, yet, blessed be God, it is fulfilled in us; there is that in all true believers, which answers the intention of the law. The favour of God, the welfare of the soul, the concerns of eternity, are the things of the Spirit, which those that are after the Spirit do mind. Which way do our thoughts move with most pleasure? Which way go our plans and contrivances? Are we most wise for the world, or for our souls? Those that live in pleasure are dead, 1Ti 5:6. A sanctified soul is a living soul; and that life is peace. The carnal mind is not only an enemy to God, but enmity itself. The carnal man may, by the power of Divine grace, be made subject to the law of God, but the carnal mind never can; that must be broken and driven out. We may know our real state and character by inquiring whether we have the Spirit of God and Christ, or not, ver. 9. Ye are not in the flesh, but in the Spirit. Having the Spirit of Christ, means having a turn of mind in some degree like the mind that was in Christ Jesus, and is to be shown by a life and conversation suitable to his precepts and example.
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.
