The principle presented by Paul concerning the gift of tongues is equally applicable to the use of the voice in prayer and social meeting. We would not have anyone who is defective in this respect cease from offering public prayer, or from bearing witness to the power and love of Christ. (CT 245.1) MC VC

I do not write these things to silence you, for there has already been too much silence in our meetings; but I write that you may consecrate your voice to Him who gave you this gift, and may realize the necessity of cultivating it so that you may edify the church by what you say. If you have acquired the habit of speaking in a low, indistinct way, you should regard it as a defect, and put forth earnest efforts to overcome, that you may honor God and edify His children. (CT 245.2) MC VC

In our devotional meetings, our voices should express by prayer and praise our adoration of the heavenly Father, that all may know that we worship God in simplicity and truth, and in the beauty of holiness. Precious indeed in this world of sin and ignorance is the gift of speech, the melody of the human voice, when devoted to the praise of Him who hath loved us and given Himself for us. (CT 245.3) MC VC

Consecration of the Voice VC

The gift of speech has been greatly abused and widely perverted from its intended purpose; but let those who claim to be children of the heavenly King awake to their responsibility, and make the most of this talent. Let no one say, “It is of no use for me to try to pray; for others do not hear me.” Rather let him say, “I will make earnest effort to overcome this God-dishonoring habit of speaking in a low, indistinct tone. I will put myself under discipline until my voice shall be audible even to those who are dull of hearing.” (CT 245.4) MC VC
