"But this Doctrine and Covenants contains the word of God to those who dwell here now. It is our book… More precious than gold, the Prophet says we should treasure it more than the riches of the whole earth. I wonder if we do? If we value it, understand it, and know what it contains, we will value it more than wealth; it is worth more to us than the riches of the earth."

Joseph Fielding Smith (Doctrines of Salvation, 3:198-99
