"What is it about Islam that continues to attract people at a time when many other religions are either stagnating or actually losing adherents? What does Islam say about God, Heaven and Hell, the life of this world and of the next, sin and forgiveness? What are the arguments for the existence of invisible beings and supernormal phenomena? M Fethullah Gülen answers these questions and many others from the viewpoints of rationality, reason, and logic. There is no demand to ?believe, or else.? Rather, he invites the readers to use their God-given intelligence to understand what they are doing here, why they are here, and where they are going. Gülen's sincerity, altruism, and love have captured millions of hearts. His followers preach, teach, and establish private schools all over the world; publish books and magazines, dailies and weeklies; broadcast television and radio programs; fund scholarships for students; and avoid politics and political ambition." -- BOOK JACKET.
