What is the fulness of the gospel?

The Lord has said that the fulness of the gospel is the “everlasting covenant,” which He has “sent forth unto the children of men” (Doctrine and Covenants 66:2). It includes everything necessary for God’s children to enter a covenant relationship with Him and receive salvation and exaltation.

The gospel is the “good news” about Jesus Christ. It is “God’s plan of salvation, made possible through the Atonement of Jesus Christ. The gospel includes the eternal truths or laws, covenants, and ordinances needed for mankind to enter back into the presence of God” (Guide to the Scriptures, “Gospel”). Many of these things had been lost. But now, through revelation to prophets, beginning with Joseph Smith, the Lord is restoring the fulness of His gospel.

With the Restoration of the fulness of His gospel, Jesus Christ “invites all of us to come unto Him and His Church, to receive the Holy Ghost, the ordinances of salvation, and to gain enduring joy” (“The Restoration of the Fulness of the Gospel of Jesus Christ: A Bicentennial Proclamation to the World,” Gospel Library).
