The Lord requires the human agent not to move by impulse in speaking, but to move calmly, speak slowly, and let the Holy Spirit give efficiency to the truth. Never think that in working yourselves up to a passion of delivery, speaking by impulse, and suffering your feelings to raise your voice to an unnaturally high key, that you are giving evidence of the great power of God upon you.... (Ev 668.1) MC VC

Your influence is to be far reaching, and your powers of speech should be under the control of reason. When you strain the organs of speech, the modulations of the voice are lost. The tendency to rapid speaking should be decidedly overcome. God claims of the human instrumentality all the service that man can give. All the talents entrusted to the human agent are to be cherished and appreciated, and used as a precious endowment of heaven. The laborers in the harvest field are God’s appointed agents, channels through which He can communicate light from heaven. The careless, improvident use of any of their God-given powers lessens their efficiency so that in an emergency, when the greatest good might be done, they are so weak and sickly and crippled that they can accomplish but little.—Special Testimonies, Series A, No. 7, pp. 9-11. (1874). (Ev 668.2) MC VC

Voice Culture Important to Minister—The teachers in our schools should not tolerate in the students ungainly attitudes and uncouth gestures, wrong intonations in reading, or incorrect accents or emphasis. Perfection of speech and voice should be urged upon every student. Because of carelessness and bad training, habits are often contracted which are great hindrances in the work of a minister who has otherwise educated talent. The student must be impressed that he has it in his power, by combining grace with effort, to make himself a man. The mental and physical capabilities with which God has adorned him may by cultivation and painstaking effort become a power to benefit his fellow men.—Manuscript 22, 1886. (Ev 668.3) MC VC
