19 Obviously, the law applies to those to whom it was given, for its purpose is to keep people from having excuses, and to show that the entire world is guilty before God. 20 For no one can ever be made right with God by doing what the law commands. The law simply shows us how sinful we are.
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.
