The Doctrine and Covenants is a book of scripture containing revelations from the Lord to the Prophet Joseph Smith and to a few other latter-day prophets. It is unique in scripture because it is not a translation of ancient documents.
The Doctrine and Covenants is one of four books of scripture used in The Church of Jesus Christ of Latter-day Saints (the other three are the Bible, the Book of Mormon, and the Pearl of Great Price).
The Lord said to the Prophet Joseph Smith, "This generation shall have my word through you" (D&C 5:10). In the Doctrine and Covenants we learn doctrines concerning the eternal nature of families, the degrees of glory awaiting men and women after this life, and the organization of Christ's Church on earth today. We also read about the covenants God makes with those who are willing to keep His commandments.
Concerning the Doctrine and Covenants, the Lord said:
"Search these commandments, for they are true and faithful, and the prophecies and promises which are in them shall all be fulfilled.
"What I the Lord have spoken, I have spoken, and I excuse not myself; and though the heavens and the earth pass away, my word shall not pass away, but shall all be fulfilled, whether by mine own voice or by the voice of my servants, it is the same" (D&C 1:37-38).
The Prophet Joseph Smith said that the Doctrine and Covenants is "the foundation of the Church in these last days, and a benefit to the world, showing that the keys of the mysteries of the kingdom of our Savior are again entrusted to man" (section heading for D&C 70).
