Romans 8:3

“For what the law could not do, etc..] This is not to be understood of “the law of the mind”, in opposition to “the law of sin”, which indeed is very feeble and impotent; man had a power originally of obeying the divine commands, but through sin he has lost his strength and power; and even a renewed mind cannot perform what it would, which is owing to the flesh, or corrupt nature; it has strong desires after holiness, and keeping all the commandments of God; but these desires cannot be fulfilled by it, and indeed without Christ it can do no good thing: nor is the ceremonial law intended, though this is weak, and there are many things it could not do; it could not expiate and atone for sin;…”

“For what the law could not do, &c.--a difficult and much controverted verse. But it is clearly, we think, the law's inability to free us from the dominion of sin that the apostle has in view; as has partly appeared already (see on Rom 8:2), and will more fully appear presently. The law could irritate our sinful nature into more virulent action, as we have seen in Rom 7:5, but it could not secure its own fulfilment. How that is accomplished comes now to be shown. in that it was weak through the flesh--that is, having to address itself to us through a corrupt nature, too strong to be influenced by mere commands and threatenings. God, &c.--The sentence is somewhat imperfect in its structure,…”

“For what the law could not do - The Law of God, the moral law. It could not free from sin and condemnation. This the apostle had fully shown in Romans 7:0. In that - Because. It was weak - It was feeble and inefficacious. It could not accomplish it. Through the flesh - In consequence of the strength of sin, and of the evil and corrupt desires of the unrenewed heart. The fault was not in the Law, which was good Romans 7:12, but it was owing to the strength of the natural passions and the sinfulness of the unrenewed heart; see Romans 7:7-11, where this influence is fully explained. God, sending his own Son - That is, God did, or accomplished, that, by sending his Son, which the Law could not…”

“For what the law - Of Moses. Could not do, in that it was weak through the flesh - Incapable of conquering our evil nature. If it could, God needed not to have sent his own Son in the likeness of sinful flesh - We with our sinful flesh were devoted to death. But God sending his own Son, in the likeness of that flesh, though pure from sin, condemned that sin which was in our flesh; gave sentence, that sin should be destroyed, and the believer wholly delivered from it. Romans 8:4”

“8:3 our sinful nature: See study note on 6:19. • in a body like the bodies we sinners have: Jesus identified with sinful people so that he could be their representative and redeem them. Paul also implies that Jesus’ incarnate nature was not exactly like ours; born of a virgin through the power of the Holy Spirit, Jesus did not inherit a sinful nature from Adam. • a sacrifice for our sins: In the Greek Old Testament, this phrase frequently describes a sin offering, and three of the eight New Testament occurrences also have this meaning (Heb 10:6, 8; 13:11). Christ was the sin offering that brought forgiveness and turned away God’s wrath. God condemned sin in Christ, our substitute, so that we…”
