Matthew 12:37 - Ellicott's Commentary On The Whole Bible

By thy words thou shalt be justified. — Stripped of the after-thoughts which have gathered round it in the later controversies of theologians, the word “justified” means, as its position here shows, the opposite of “condemned,” the being “acquitted” either on a special charge or on a general trial of character. In this sense we are able to understand (without entering into the labyrinth of logomachies in which commentators on the Epistles have too often entangled themselves) how it is that men are said to be justified by faith (Romans 3:28 et al.), justified by works (James 2:24), justified — as here — by words. All three — faith, works, words — are alike elements of a man’s character, making or showing what he is. Faith, implying trust and therefore love, justifies as the root element of character; “words,” as its most spontaneous manifestation; works, as its more permanent results. Of the words and the works men can in some measure judge, and they are the tests by which a man should judge himself. The faith which lies deeper in the life is known only to God, and it is therefore by faith rather than by works that a man is justified before God, though the faith is no true faith unless it moulds the character and therefore enables the man to pass the other tests also.
