In all our ministerial work, more attention should be given to the culture of the voice. We may have knowledge, but unless we know how to use the voice correctly, our work will be a failure. Unless we can clothe our ideas in appropriate language, of what avail is our education? Knowledge will be of little advantage to us unless we cultivate the talent of speech; but it is a wonderful power when combined with the ability to speak wise, helpful words, and to speak them in a way that will command attention. GW 86.1
Students who expect to become workers in the cause of God should be trained to speak in a clear, straightforward manner, else they will be shorn of half their influence for good. The ability to speak plainly and clearly, in full, round tones, is invaluable in any line of work. This qualification is indispensable in those who desire to become ministers, evangelists, Bible-workers, or canvassers. Those who are planning to enter these lines of work should be taught to use the voice in such a way that when they speak to people about the truth, a decided impression for good will be made. The truth must not be marred by being communicated through defective utterance. GW 86.2
The canvasser who can speak clearly and distinctly about the merits of the book he wishes to sell, will find this a great help in his work. He may have an opportunity to read a chapter of the book, and by the music of his voice and the emphasis placed on the words, he can make the scene presented stand out as clearly before the mind of the listener as if it could actually be seen. GW 86.3
The one who gives Bible-readings in the congregation or in the family should be able to read with a soft, musical cadence which will charm the hearers. GW 87.1
Ministers of the gospel should know how to speak with power and expression, making the words of eternal life so expressive and impressive that the hearers cannot but feel their weight. I am pained as I hear the defective voices of many of our ministers. Such ministers rob God of the glory He might have if they had trained themselves to speak the word with power. GW 87.2
