Do people covet prominent callings because they think a chief seat indicates validation from the Lord? Did Jesus call Judas as an apostle to remind us that devils can be called to even the highest of positions? Isn’t the Holy Ghost what God sends us to validate our efforts?
“Now this is the commandment: Repent, all ye ends of the earth, and come unto me and be baptized in my name, that ye may be sanctified by the reception of the Holy Ghost, that ye may stand spotless before me at the last day.” (3 Nephi 27:20)
“…the Comforter, which showeth all things, and teacheth the peaceable things of the kingdom.” (D&C 39:6)
In addition to the Holy Ghost, wouldn’t the next level of heavenly validation entail visitations from heavenly messengers?
“Or have angels ceased to appear unto the children of men? Or has he withheld the power of the Holy Ghost from them? Or will he, so long as time shall last, or the earth shall stand, or there shall be one man upon the face thereof to be saved? Behold I say unto you, Nay; for it is by faith that miracles are wrought; and it is by faith that angels appear and minister unto men; wherefore, if these things have ceased wo be unto the children of men, for it is because of unbelief, and all is vain.” (Moroni 7:36-37)
Since we’re under no obligation to obey any Church leader that doesn’t love and serve us in pure love and humility, is there really much of a risk in allowing bad, or even very average people to receive “important” callings? In fact, isn’t the only real risk, in terms of impact on the members associated with those in a leadership position, that the members themselves might twist such roles into something they were never intended to be? As the Prophet Joseph taught:
“We have heard men who hold the priesthood remark, that they would do anything they were told to do by those who presided over them, if they knew it was wrong; but such obedience as this is worse than folly to us; it is slavery in the extreme; and the man who would thus willingly degrade himself should not claim a rank among intelligent beings, until he turns from his folly. A man of God… would despise the idea.” (Millennial Star, vol.14 #38, pp. 593-95)
Thus, callings are really just opportunities to serve others in righteousness; no more, no less.
