At the end of D&C 121, we read about how priesthood holders ought to conduct themselves. For example, priesthood holders should be gentle, be kind, and not be hypocritical.
Consider verse 43:
Reproving betimes with sharpness, when moved upon by the Holy Ghost; and then showing forth afterwards an increase of love toward him whom thou hast reproved, lest he esteem thee to be his enemy;
I have heard people interpret this to mean that it?¢‚Ç¨‚Ñ¢s okay to be critical or cutting as long as one is loving afterward. While sharp certainly can mean ?¢‚Ç¨¬ùcutting?¢‚Ç¨‚Ñ¢, I wonder if it may be referring to something else, particularly given all the other qualities mentioned in the preceding verses.
Sharpness can also mean ?¢‚Ç¨¬ùacuteness?¢‚Ç¨¬ù and, ?¢‚Ç¨¬ùclarity?¢‚Ç¨¬ù. Using these definitions, the verse could be suggesting that when we reprove others, we should do it in a way to make our points clear, or perhaps do it with a clear mind. This, of course, would be more in line with the preceding verses.
