D&C 78

I find it quite comforting as the Lord says -

"...Hearken unto me, saith the Lord your God, who are ordained unto the high priesthood of my church, who have assembled yourselves together;
2 And listen to the counsel of him who has ordained you from on high..."  (Doctrine and Covenants | Section 78:1 - 2)

Whether it be being ordained to an office in the priesthood or being set apart for a calling, the Lord is suggesting that it is He that is doing...of course by delegation.
