12:37 By thy words thou shalt be justified, etc. Acquitted or condemned in the day of judgment. To justify is the opposite of to condemn. Those who confess Christ with the mouth (Ro 10:9) shall be saved; those who deny him will be lost. Words have a weighty influence on our eternal destiny.
12:37 For by thy words (as well as thy tempers and works) thou shalt then be either acquitted or condemned. Your words as well as actions shall he produced in evidence for or against you, to prove whether you was a true believer or not. And according to that evidence you will either be acquitted or condemned in the great day.
12:33-37 Men's language discovers what country they are of, likewise what manner of spirit they are of. The heart is the fountain, words are the streams. A troubled fountain, and a corrupt spring, must send forth muddy and unpleasant streams. Nothing but the salt of grace, cast into the spring, will heal the waters, season the speech, and purify the corrupt communication. An evil man has an evil treasure in his heart, and out of it brings forth evil things. Lusts and corruptions, dwelling and reigning in the heart, are an evil treasure, out of which the sinner brings forth bad words and actions, to dishonour God, and hurt others. Let us keep constant watch over ourselves, that we may speak words agreeable to the Christian character.
