Romans 8:4

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" (Rom 1:17; Rom 3:21; Rom 4:5-6; Rom 5:17-18, Rom 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 (Gen 48:15; Psa 1:1; Isa 2:5; Mic 4:5; Eph 4:17; Jo1 1:6-7). not after--that is, according to the dictates of the flesh, but after the spirit--From Rom 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.

The apostle, having fully explained the doctrine of justification, and pressed the necessity of sanctification, in this chapter applies himself to the consolation of the Lord's people. Ministers are helpers of the joy of the saints. "Comfort ye, comfort ye my people," so runs our commission, Isa 40:1. It is the will of God that his people should be a comforted people. And we have here such a draught of the gospel charter, such a display of the unspeakable privileges of true believers, as may furnish us with abundant matter for joy and peace in believing, that by all these immutable things, in which it is impossible for God to lie, we might have strong consolation. Many of the people of God have, accordingly, found this chapter a well-spring of comfort to their souls, living and dying, and have sucked and been satisfied from these breasts of consolation, and with joy drawn water out of these wells of salvation. There are three things in this chapter: I. The particular instances of Christians' privileges (v. 1-28). II. The ground thereof laid in predestination (Rom 8:29, Rom 8:30). III. The apostle's triumph herein, in the name of all the saints (Rom 8:31 to the end).

8:4 just requirement of the law . . . fully satisfied for (Greek en, “in”) us: The Greek preposition en might indicate that the law is fulfilled in us because of our connection with Jesus Christ, who perfectly fulfilled the law for us. It could also mean that by setting us free from sin’s power, Jesus Christ enables us to please God and fulfill the true intention of the law. • As in the Old Testament (see Gen 6:3, 12; Ps 78:39; Isa 40:6), sinful nature refers to human weakness and bondage to sin (also in Rom 8:5-9, 12-13). Paul uses the phrase to describe the conflict between the ingrained human tendency to sin and the Holy Spirit.
