“While the inhabitants of the earth are bestowing all their ability, both mental and physical, upon perishable objects, those who profess to be Latter-day Saints, who have the privilege of receiving and understanding the principles of the holy gospel, are in duty bound to study and find out, and put in practice in their lives, those principles that are calculated to endure, and that tend to a continual increase in this, and in the world to come” (Teachings of Presidents of the Church: Brigham Young, p. 193).
