20 Because by the works of the law, no flesh will be justified in his sight. 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.
