Adam Clarke

But that no man is justified by the law - By the observance of the law, suppose he had even continued in all things that are written in it to do them, is evident; for the Prophet Habakkuk, Hab 2:4, has declared, under the direct influence of the Spirit of God, The just shall live by faith; or, he who is just by faith shall live: therefore this justification comes not by works, or the observance of the law, but by faith.
