20 Because by the works of the law no man is able to have righteousness in his eyes, for through the law comes the knowledge of sin.

Matthew Henry's Commentary on Romans 3:20

Commentary on Romans 3:19-20

(Read Romans 3:19-20)

It is in vain to seek for justification by the works of the law. All must plead guilty. Guilty before God, is a dreadful word; but no man can be justified by a law which condemns him for breaking it. The corruption in our nature, will for ever stop any justification by our own works.
