Romans 3:20

“Therefore by the deeds of the law, etc..] Hence it most clearly appears, that there can be no justification before God by the law, since it stops the mouths of men, and pronounces them guilty: by “the deeds of the law” are meant, works done in obedience to it, as performed by sinful men, which are very imperfect; not as performed by Adam in innocence or by Christ in our nature whose works were perfect; but as performed by sinful men and of themselves, and not as performed in and by Christ for them who is the fulfilling end of the law for righteousness to all believers: now by such works as these whether wrought before or after conversion, with or without the strength and grace of Christ,…”

“Therefore by the deeds of--obedience to the law there shall no flesh be justified--that is, be held and treated as righteous; as is plain from the whole scope and strain of the argument. in his sight--at His bar (Psa 143:2). for by the law is the knowledge of sin--(See on Rom 4:15; Rom 7:7; and Jo1 3:4). Note, How broad and deep does the apostle in this section lay the foundations of his great doctrine of Justification by free grace--in the disorder of man's whole nature, the consequent universality of human guilt, the condemnation, by reason of the breach of divine law, of the whole world, and the impossibility of justification before God by obedience to that violated law! Only when these…”

“By the deeds of the law - By works; or by such deeds as the Law requires. The word “Law” has, in the Scriptures, a great variety of significations. Its strict and proper meaning is, a rule of conduct prescribed by superior authority. The course of reasoning in these chapters shows the sense in which the apostle uses it here. He intends evidently to apply it to those rules or laws by which the Jews and Gentiles pretended to frame their lives; and to affirm that people could be justified by no conformity to those laws. He had shown Romans 1:0 that “the pagan, the entire Gentile world,” had violated the laws of nature; the rules of virtue made known to them by reason, tradition, and conscience.…”

“No flesh shall be justified - None shall be forgiven and accepted of God. By the works of the law - On this ground, that he hath kept the law. St. Paul means chiefly the moral part of it, Rom 3:9, Rom 3:19, Rom 2:21, Rom 2:26; &c. which alone is not abolished, Rom 3:31. And it is not without reason, that he so often mentions the works of the law, whether ceremonial or moral; for it was on these only the Jews relied, being wholly ignorant of those that spring from faith. For by the law is only the knowledge of sin - But no deliverance either from the guilt or power of it. Romans 3:21”

“3:20 By doing what the law commands refers to obeying the requirements of the law of Moses. While this phrase refers to Jews, the principle extends to all people. If Jews cannot be put in right relationship with God by obeying the law God gave them, certainly other people cannot establish such a relationship through good deeds.”
