No man should regard himself as qualified to enter the ministry until by persevering effort he has overcome every defect in his utterance. If he attempts to speak to the people without knowing how to use the talent of speech, half his influence is lost, for he has little power to hold the attention of a congregation. GW 87.3
Whatever his calling, every person should learn to control the voice, so that when something goes wrong, he will not speak in tones that stir the worst passions of the heart. Too often the speaker and the one addressed speak sharply and harshly. Sharp, dictatorial words, uttered in hard, rasping tones, have separated friends and resulted in the loss of souls.... GW 87.4
In the social meeting there is special need of clear, distinct utterance, that all may hear the testimonies borne and be benefited by them. Difficulties are removed and help is given as in social meeting God's people relate their experiences. But too often the testimonies are borne with faulty, indistinct utterance, and it is impossible to gain a correct idea of what is said. Thus the blessing is often lost. GW 87.5
Let those who pray and those who speak pronounce their words properly, and speak in clear, distinct, even tones. Prayer, if properly offered, is a power for good. It is one of the means used by the Lord to communicate to the people the precious treasures of truth. But prayer is not what it should be, because of the defective voices of those who utter it. Satan rejoices when the prayers offered to God are almost inaudible. GW 88.1
Let God's people learn how to speak and pray in a way that will properly represent the great truths they possess. Let the testimonies borne and the prayers offered be clear and distinct. Thus God will be glorified. Let all make the most of the talent of speech. GW 88.2
God calls for a higher, more perfect ministry. He is dishonored by the imperfect utterance of the one who by painstaking effort could become an acceptable mouthpiece for Him. The truth is too often marred by the channel through which it passes. GW 88.3
The Lord calls upon all who are connected with His service to give attention to the cultivation of the voice, that they may utter in an acceptable manner the great and solemn truths He has entrusted to them. Let none mar the truth by defective utterance. Let not those who have neglected to cultivate the talent of speech suppose that they are qualified to minister; for they have yet to obtain the power to communicate. GW 88.4
