But if you don't understand what's so powerful about a book, and you want to know, then you really should give it a try—I might say that the last chapter of Moroni especially addresses this.
Well, I've now read the last chapter of Moroni, which is the last book of the Book of Mormon. The prophet takes his leave of his people, promises that God, the Son, and the Holy Ghost will reveal the truth of these things to those who sincerely pray, enjoins them to practice faith, hope, and charity and avoid despair, and promises to see them in the hereafter.
I don't feel any urge to read this as other than fiction.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
