The book, ‘The Glorious Appearing,’ by Tim LaHaye and Jerry B. Jenkins, has already sold 1.9 million copies even before it goes on official sale March 30. That makes it one of the top-selling books of the year. “The advance sales indicate that as well as a major subject of discussion in church groups and in the news media. The series is based on Dr. LaHaye’s reading of the Book of Revelation in the Bible.”
