President James E. Faust (1920–2007) of the First Presidency spoke of how the standard works of the Church have been the principal means of restoring lost truths:
“The Apostle John saw in vision the time when an angel would come to the earth as part of the Restoration of the gospel. That angel was Moroni, who appeared to the Prophet Joseph Smith. He directed Joseph to the place where golden plates containing ancient writings were deposited. Joseph Smith then translated these plates by the gift and power of God, and the Book of Mormon was published. This is a record of two groups of people who lived centuries ago on the American continent. Little was known about them before the coming forth of the Book of Mormon. But more importantly, the Book of Mormon is another testament of Christ. It restored precious truths concerning the Fall, the Atonement, the Resurrection, and life after death.
“Prior to the Restoration, the heavens had been closed for centuries. But with prophets and apostles upon the earth once more, the heavens were opened once again with visions and revelations. Many of the revelations that came to the Prophet Joseph Smith were written down in a book that came to be known as the Doctrine and Covenants. This contains further insights about principles and ordinances and is a valuable source concerning the structure of the priesthood. In addition, we have another canon of scripture called the Pearl of Great Price. It contains the book of Moses, which came by revelation to the Prophet Joseph Smith, and the book of Abraham, which he translated from a purchased Egyptian scroll. From these we learn not only a great deal more about Moses, Abraham, Enoch, and other prophets but also many more details about the Creation. We learn that the gospel of Jesus Christ was taught to all of the prophets from the beginning—even from the time of Adam” (in Conference Report, Apr. 2006, 68; or Ensign, May 2006, 67–68).
The Joseph Smith Translation of the Bible also helps restore many plain and precious truths. The Joseph Smith Translation is “a revision or translation of the King James Version of the Bible in English, which the Prophet Joseph Smith began in June 1830. He was commanded by God to make the translation and regarded it as part of his calling as a prophet. …
“The Joseph Smith Translation has restored some of the plain and precious things that have been lost from the Bible (1 Nephi 13). Although it is not the official Bible of the Church, this translation does offer many interesting insights and is very valuable in understanding the Bible. It is also a witness for the divine calling and ministry of the Prophet Joseph Smith” (Guide to the Scriptures, “Joseph Smith Translation”; see also 2 Nephi 3:11; History of the Church, 1:238).
With continuing revelation in the Lord’s Church, the process of bringing the plain and precious doctrines and principles of the gospel to people throughout the world is an ongoing process. The conference reports and other inspired writings from the Lord’s apostles and prophets are vital for gospel understanding of the plain and precious truths.
