Verses 18–30 in 1 Nephi 14 refer to the book of Revelation, the last book in the New Testament, written by the Apostle John. Nephi saw the events of our day but was not allowed to write them because it was John’s responsibility. Verse 26 could have reference to the portion of the Book of Mormon that was sealed. (For further information about the sealed portion, see 2 Nephi 27:7; 3 Nephi 26:7–11; Ether 4:7.)
