God has given us the gift of speech that we may recite to others the dealing of God with us, that his love and compassion may touch their hearts, and that praise may also arise from their souls to him who hath called them out of darkness into his marvelous light. The Lord has said, “Ye are my witnesses.” [ Isaiah 43:10 .] But all who are called to be witnesses for Christ must learn of him, that they may be efficient witnesses. As children of the heavenly King, you should educate yourselves to bear testimony in a clear, distinct voice, and in such a manner that no one may have the impression that you are reluctant to speak of the mercies of the Lord. In social meeting, prayer should be offered so that all may be edified, and those who take part in this exercise should follow the example given us in the Lord's beautiful prayer for the world. The prayer of Jesus is simple, clear, comprehensive, and yet not long and spiritless as are the dry prayers that are often offered in public. These …
"Ye are my witnesses, saith the Lord, and my servant whom I have chosen: that ye may know and believe me, and understand that I am he: before me there was no God formed, neither shall there be after me."
Ellen White directly references Isaiah 43:10 in this passage.
“And even things without life giving sound, whether pipe or harp, except they give a distinction in the sounds, how shall it be known what is piped or harped? For if the trumpet give an uncertain sound, who shall prepare himself to the battle? So likewise ye, except ye utter by the tongue words easy to be understood, how shall it be known what is spoken? for ye shall speak into the air. There are, it may be, so many kinds of voices in the world, and none of them is without signification. Therefore if I know not the meaning of the voice, I shall be unto him that speaketh a barbarian, and he that speaketh shall be a barbarian unto me. Even so ye, forasmuch as ye are zealous of spiritual gifts, seek that ye may excel to the edifying of the church,” [ 1 Corinthians 14:7-12 .] “No man liveth unto himself.” In all our religious services we should seek to conduct ourselves in a way that we may edify others, working as much as lies in our power for the perfection of the church. “Wherefore let …

"Wherefore let him that speaketh in an unknown tongue pray that he may interpret. For if I pray in an unknown tongue, my spirit prayeth, but my understanding is unfruitful. What is it then? I will pray with the spirit, and I will pray with the understanding also: I will sing with the spirit, and I will sing with the understanding also. Else when thou shalt bless with the spirit, how shall he that occupieth the room of the unlearned say Amen at thy giving of thanks, seeing he understandeth not what thou sayest? For thou verily givest thanks well, but the other is not edified. I thank my God, I speak with tongues more than ye all: Yet in the church I had rather speak five words with my understanding, that by my voice I might teach others also, than ten thousand words in an unknown tongue."
Ellen White directly references 1 Corinthians 14:13-19 in this passage.
