We may have knowledge, but unless the habit is acquired of using 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 value 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. (CT 217.1) MC VC

Let all guard against becoming annoyed in spirit because they have to be drilled in these common branches. It should be impressed upon students that they will themselves be educators of others, and for this reason they should strive earnestly to improve. (CT 217.2) MC VC

To learn to tell convincingly and impressively that which one knows is of especial value to those who desire to be workers in the cause of God. The more expression we can put into the words of truth, the more effective these words will be on those who hear. A proper presentation of the Lord’s truth is worthy of our highest effort. (CT 217.3) MC VC

Unless students who are preparing for work in the cause of God are trained to speak in a clear, straightforward manner, they will be shorn of half their influence for good. Whatever his calling is to be, the student should learn to control the voice. The ability to speak plainly and distinctly, in full, round tones, is invaluable in any line of work, and it is indispensable to those who desire to become ministers, evangelists, Bible workers, or canvassers. (CT 217.4) MC VC
