What does tongues of angels mean?
Elder Jeffrey R. Holland gave a most moving talk in General Conference regarding this subject in 2007 (The Tongue of Angels). In this talk he states:
“So, brothers and sisters, in this long eternal quest to be more like our Savior, may we try to be “perfect” men and women in at least this one way now—by offending not in word, or more positively put, by speaking with a new tongue, the tongue of angels. Our words, like our deeds, should be filled with faith and hope and charity, the three great Christian imperatives so desperately needed in the world today. With such words, spoken under the influence of the Spirit, tears can be dried, hearts can be healed, lives can be elevated, hope can return, confidence can prevail. I pray that my words, even on this challenging subject, will be encouraging to you, not discouraging, that you can hear in my voice that I love you, because I do. More importantly, please know that your Father in Heaven loves you and so does His Only Begotten Son. When They speak to you—and They will—it will not be in the wind, nor in the earthquake, nor in the fire, but it will be with a voice still and small, a voice tender and kind. It will be with the tongue of angels.”
