I believe that Latter-day Saints who give unselfish service and sacrifice in worshipful imitation of our Savior adhere to eternal values to a greater extent than any other group of people. Latter-day Saints look on their sacrifices of time and means as a part of their schooling and qualifying for eternity. This is the truth revealed in the Lectures on Faith, which teach that ‘a religion that does not require the sacrifice of all things never has power sufficient to produce the faith necessary unto life and salvation . . . It is through this sacrifice, and this only, that God has ordained that man should enjoy eternal life.
