19 Now we know that whatever the things the law says, it speaks to those under the law, that every mouth may be stopped, and all the world be under judgment to God. 20 Wherefore by works of law no flesh shall be justified before him; for by law [is] knowledge of sin.
Matthew Henry's Commentary on Romans 3:19-20
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.
