"Let the Saints remember that great things depend on their individual exertion," Joseph Smith cautioned, "and that they are called to be co-workers with us and the Holy Spirit in accomplishing the great work of the last days; and in consideration of the extent, the blessings and glories of the same, let every selfish feeling be not only buried, but annihilated; and let love to God and man predominate, and reign triumphant in every mind, that their hearts may . . . comprehend all things, present, past and future, and come behind in no gift, waiting for the coming of the Lord Jesus Christ" (History of the Church, 4:230–31).
During His mortal ministry, Jesus Christ prayed to the Father, "thy kingdom come" (Matthew 6:10). "Prepare ye the way of the Lord," is the instruction to this dispensation. "Pray unto the Lord, call upon his holy name, make known his wonderful works among the people" (D&C 65:3–4). The revelation through Joseph Smith continued: "Call upon the Lord, that his kingdom may go forth upon the earth, that the inhabitants thereof may receive it, and be prepared for the days to come, in the which the Son of Man shall come down in heaven, clothed in the brightness of his glory, to meet the kingdom of God which is set up on the earth" (D&C 65:5).
"Let there be no misunderstanding. We are witnesses of Christ. He is our Savior. . . . But we are also witnesses of Joseph Smith, by whom we know of Christ, and who is the legal administrator to whom power was given to bind on earth and seal in heaven, that all men from his day forward might be heirs of salvation" (Bruce R. McConkie, "Joseph Smith: The Mighty Prophet of the Restoration," Ensign, May 1976, 97).
