“Joseph Smith, the Prophet and Seer of the Lord, Has Done More, Save Jesus Only, for the Salvation of Men in This World, than Any Other Man”
Doctrine and Covenants 135:3
3 Joseph Smith, the Prophet and Seer of the Lord, has done more, save Jesus only, for the salvation of men in this world, than any other man that ever lived in it. In the short space of twenty years, he has brought forth the Book of Mormon, which he translated by the gift and power of God, and has been the means of publishing it on two continents; has sent the fulness of the everlasting gospel, which it contained, to the four quarters of the earth; has brought forth the revelations and commandments which compose this book of Doctrine and Covenants, and many other wise documents and instructions for the benefit of the children of men; gathered many thousands of the Latter-day Saints, founded a great city, and left a fame and name that cannot be slain. He lived great, and he died great in the eyes of God and his people; and like most of the Lord’s anointed in ancient times, has sealed his mission and his works with his own blood; and so has his brother Hyrum. In life they were not divided, and in death they were not separated!
President Joseph F. said:
“The work in which Joseph Smith was engaged was not confined to this life alone, but it pertains as well to the life to come, and to the life that has been. In other words, it relates to those who have lived upon the earth, to those who are living and to those who shall come after us. It is not something which relates to man only while he tabernacles in the flesh, but to the whole human family from eternity to eternity.”
