“The power of God, here represented as the Lord making bare his arm, will be manifest by the taking of the gospel and its eternal covenants to all the nations and peoples of the earth. That same God who delivered Israel from the might of Egypt will in the latter days show again his power with greater miracles than those witnessed at the hands of Moses. … Missionaries must go to the lands that have not yet received them, until the gospel ‘has penetrated every continent, visited every clime, swept every country, and sounded in every ear, till the purposes of God shall be accomplished, and the Great Jehovah shall say the work is done’ ([History of the Church,] 4:540)” (McConkie and Millet, Doctrinal Commentary on the Book of Mormon, 1:172).
