D&C 53

The Lord told Algernon Sidney Gilbert - 

"Behold, these are the first ordinances which you shall receive; and the residue shall be made known in a time to come, according to your labor in my vineyard.

7 And again, I would that ye should learn that he only is saved who endureth unto the end."  (Doctrine and Covenants 53:6–7)

I believe the word ordinances had reference to present term "setting apart" or callings.  I believe this applies to all.  Continued callings will depend on faithfulness.
