How We Speak To Each Other
"Like all gifts 'which cometh from above,' words are 'sacred, and must be spoken with care, and by constraint of the Spirit' (D&C 63:64). "It is with this realization of the power and sanctity of words that I wish to caution us, if caution is needed, regarding how we speak to each other and how we speak of ourselves. "There is a line from the Apocrypha which puts the seriousness of this issue better than I can. It reads, 'The stroke of the whip maketh marks in the flesh: but the stroke of the tongue breaketh the bones' (Ecclesiasticus 28:17)."
