If someone turns from these restored doctrines, where will he go to learn the true nature of God as taught in the grove of trees? Where will he go to find the doctrines of the premortal existence, baptism for the dead, and eternal marriage? And where will he go to find the sealing powers that can bind husbands and wives and children beyond the grave?
Through Joseph Smith have been restored all the powers, keys, teachings, and ordinances necessary for salvation and exaltation. You cannot go anywhere else in the world and get that. It is not to be found in any other church. It is not to be found in any philosophy of man or scientific digest or individual pilgrimage, however intellectual it may seem. Salvation is to be found in one place alone, as so designated by the Lord Himself when He said that this is “the only true and living church upon the face of the whole earth” (D&C 1:30).
I bear my witness that Joseph Smith was the prophet of the Restoration, just as he claimed to be. I echo the strains of that stirring hymn: “Praise to the man who communed with Jehovah!” (“Praise to the Man,” Hymns, no. 27).
