Lost books are among the treasures yet to come forth. Over twenty of these are mentioned in the existing scriptures. Perhaps most startling and voluminous will be the records of the lost tribes of Israel (see 2 Ne. 29:13). We would not even know of the impending third witness for Christ except through the precious Book of Mormon, the second witness for Christ! This third set of sacred records will thus complete a triad of truth. Then, just as the Perfect Shepherd has said, “My word also shall be gathered in one” (2 Ne. 29:14). There will be “one fold and one shepherd” (1 Ne. 22:25) in a welding together of all the Christian dispensations of human history (see D&C 128:18).
Whereas previous prophets were sometimes left to surmise—as Moroni supposed the Jews also had a record of the Creation from Adam on down (see Ether 1:3) —ours, instead, is a time of fulness, including “things which never have been revealed from the foundation of the world” (D&C 128:18). Moreover, “and the day cometh that the words of the book which were sealed shall be read upon the house tops; and they shall be read by the power of Christ; and all things shall be revealed unto the children of men which ever have been among the children of men, and which ever will be even unto the end of the earth” (2 Ne. 27:11; see also 2 Ne. 30:16, 18; Ether 4:7; D&C 101:32; D&c 121:28).
Thus, just as there will be many more Church members, families, wards, stakes, and temples—later on, there will also be many more nourishing and inspiring scriptures. However, we must first feast worthily upon that which we already have!
