The only sure way to know for yourself is through the power of the Holy Ghost. The last chapter in the Book of Mormon invites anyone who reads it, ponders it, and sincerely wants to know if it is true to ask Heavenly Father in the name of Jesus Christ. Those who take this approach will know by the power of the Holy Ghost that the book is true (see Moroni 10:3–5). Millions of members of the Church have prayed and know through the witness of the Holy Ghost that the Book of Mormon is true. (For more on this topic, see 80 in this issue.)
