The Nephites and the Lamanites are not the only people who will be judged by the things recorded in the Book of Mormon. The same judgment will come on the members of the Church who have read the book but not lived by its precepts. John the Revelator recorded, I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works (Rev 20:12). Nephi explains that the Book of Mormon is one of those books out of which the dead were judged (2 Nephi 25:18). Nephi warns, the words which I have spoken shall stand as a testimony against you; for they are sufficient to teach any man the right way (2 Nephi 25:28).

"Do eternal consequences rest upon our response to this book? Yes, either to our blessing or our condemnation. Every Latter-day Saint should make the study of this book a lifetime pursuit. Otherwise he is placing his soul in jeopardy and neglecting that which could give spiritual and intellectual unity to his whole life. There is a difference between a convert who is built on the rock of Christ through the Book of Mormon and stays hold of that iron rod, and one who is not." (A Witness and a warning, pp. 7-8 as taken from Latter-day Commentary on the Book of Mormon compiled by K. Douglas Bassett, p. 152)

"For me there could be no more impelling reason for reading the Book of Mormon than this statement of the Lord that we shall be judged by what is written in it." (Conference Report, Apr. 1960, pp. 110-111 as taken from Latter-day Commentary on the Book of Mormon compiled by K. Douglas Bassett, p. 152)
