He has given us grand and solemn truths to impart to those who are in darkness. Let us not mar these truths by imperfect utterance. God has given us voices that we may speak His truth. He desires that the music of the voice shall aid in impressing His word upon minds. 1NL 131.3
We should train ourselves to take deep, full inspirations, and to speak clearly and distinctly. The voice should not be dropped at the end of a sentence, so that the closing words are hardly audible. 1NL 131.4
