Proper Use of Vocal Organs—Careful attention and training should be given to the vocal organs. They are strengthened by right use, but become enfeebled if used improperly. Their excessive use, as in preaching long sermons, will, if often repeated, not only injure the organs of speech, but will bring an undue strain upon the whole nervous system. The delicate harp of a thousand strings becomes worn, gets out of repair, and produces discord instead of melody. {Ev 667.1}

Ordentlig brug af stemme-organerne. – Stemmeorganerne bør have omhyggelig opmærksomhed og oplæring. De styrkes ved rigtig brug, men svækkes hvis de bruges utilbørligt. Bruges de overdrevent, som at holde lange prædikener, vil det, hvis det ofte gentages, ikke kun skade taleorganerne, men belaste hele nervesystemet for meget. Den fintfølende harpe på tusindvis strenge, bliver træt, og kommer ud af stemning, og laver disharmoni i stedet for melodier.
