The scriptures often speak of “the rest of the Lord.” After quoting Moroni 7:3, President Joseph F. Smith (1838–1918) wrote:
“This is a very significant passage. The rest here referred to is not physical rest, for there is no such thing as physical rest in the Church of Jesus Christ. Reference is made to the spiritual rest and peace which are born from a settled conviction of the truth in the minds of men. We may thus enter into the rest of the Lord today, by coming to an understanding of the truths of the gospel. … Not all need to seek this rest, for there are many who now possess it, whose minds have become satisfied, and who have set their eyes upon the mark of their high calling with an invincible determination in their hearts to be steadfast in the truth, and who are treading in humility and righteousness the path marked out for the Saints who are complacent followers of Jesus Christ. …
“I thank our Father that I have come to a knowledge of this truth, that I know that Jesus is the Christ, in whom alone there is rest and salvation. As God lives, they are deceived who follow men and their philosophies; but happy are they who enter into the rest of the peaceable followers of Christ, obtaining sufficient hope from this time henceforth until they shall rest with him in heaven” (Gospel Doctrine, 5th ed. [1939], 126, 128).
