The term “mysteries of God” as used in the Book of Mormon (Mosiah 1:3) includes the saving principles of the gospel of Jesus Christ. They are termed mysteries not because they are mysterious or difficult to understand, but because they are revealed from God based upon our faith and obedience. They are intended to lead God’s children to eternal life. “A mystery is a truth that cannot be known except through divine revelation—a sacred secret. … In our day such great truths as those pertaining to the restoration of the Priesthood, the work for the dead, and the re-establishment of the Church are ‘mysteries,’ because they could not have been discovered except by revelation” (Hyrum M. Smith and Janne M. Sjodahl, The Doctrine and Covenants Commentary, rev. ed. [1972], 141).
