"Who has seen such marvelous things as Jesus did among the Nephites? And who has heard such wondrous words of divine wisdom as fell from his lips on the American continent? To our shame we know only the hundredth part. Our friend Mormon -- the prophet -- historian who has given us such as we do have -- at this point in his inspired writing said of the teachings of the Blessed One, which he so freely gave to the spiritually attuned ears in the New World: (quotes 3 Nephi 26:3-5).
"In the providences of the Lord, we have slivers and fragments of what Jesus gave the Nephites, Sections 29, 45, 63, 76, 77, 88, 93, 101, 107, 132, 133, and 138 in the Doctrine and Covenants, and the books of Moses and Abraham in the Pearl of Great Price, all contain truths of transcendent worth about the doings of Deity from the beginning to the end. But what we have is only the milk of the present, which prepares us for the meat of the future. We do not have what he told the Nephites, and we do not have what he revealed to the brother of Jared, nor will we until the sealed portion of the Book of Mormon comes forth." (Mortal Messiah, book 4, p. 368-9)
