According to John Tvedtnes, anyone can make a promise to return to a particular subject and give further details, but it if Joseph Smith would have been making up the Book of Mormon narrative as he went along in dictation (which he dictated only once through to Oliver Cowdery) it would have been difficult for Joseph Smith to fulfill all such promises. As an abridger of the Nephite records, Mormon makes several important promises which are later fulfilled. One example is found in 3 Nephi 18:36-37. Here Mormon wrote how Jesus had given the twelve disciples "power to give the Holy Ghost. And I will show unto you hereafter that this record is true." In 3 Nephi 19:13, he told how the Holy Ghost fell on the twelve after their baptism, and in 4 Nephi 1:1, he wrote that those baptized by the twelve "did also receive the Holy Ghost." But it was Moroni who quoted Christ's actual words to the twelve (left out by Mormon in 3 Nephi 18): "ye shall have power that to him upon whom ye shall lay your hands, ye shall give the Holy Ghost" (Moroni 2:2), then adding, "and on as many as they laid their hands, fell the Holy Ghost" [John A. Tvedtnes, "Mormon As an Abridger of Ancient Records," in The Most Correct Book, pp. 9-10]
