I remember a friend of mine telling me of an exchange I found unbelievable, but I knew it was not only true, it probably had happened many times.
It seems they were having a discussion in their priesthood quorum about D&C 121 (where we're told how to exercise proper persuasion as priesthood holders – kindness, gentleness, meekness, love unfeigned, etc. -- see verses 41-42). When it came to the "reproving betimes with sharpness" (v. 43) verse, a brother said out loud that this verse gave him license to yell at his wife when she was out of line.
As my friend told me this story, I reflected on some solid teaching I received on my mission from Theodore M. Burton, then a member of First Quorum of the Seventy who instructed our zone conference. He said as a chemist he likened the "sharpness" in that verse to the sharpness of a clear photograph, not the sharpness of an acid. That image has always stuck with me, as has his rush to the second part of that verse ("showing forth an increase of love").
I remembered this story the other day as I read in Moses 4:22 the Lord's instructions to Eve that her husband was to "rule" over her. Someone in our class recalled President Kimball's discussion on that point suggesting that the word "preside" could well replace the word rule.
But the real nugget for me came in the next chapter, where we read in verse 4, "And Adam and Eve, his wife, called upon the name of the Lord, and they heard the voice of the Lord from the way toward the Garden of Eden, speaking unto them…" I was struck that Adam and Eve were praying together, and that they received divine guidance together.
The Family, A Proclamation to the World teaches, "In these sacred responsibilities [of presiding and nurturing], fathers and mothers are obligated to help one another as equal partners."
The cool thing for me in the Moses verses is that Adam and Eve approached their condition together: they prayed together and they received inspiration together. A great model to emulate, if you ask me.
