You found out the book of this religion, and you saw that it has answers to just about everything, and every predictions in there is true and will be true from the beginning of the time to the end of the universe. The book has every single answer you need in your life, and you can use the book to cheat through life. You can be the richest man in the world by simply selling this book.
