Heaven is for Real is one of the most popular, with the book selling more than 10 million copies. The movie generated more than $91 million in box office receipts, and millions more in DVD sales.
The multi-million-selling 90 Minutes in Heaven actually preceded it, even though the movie version didn’t release until after Heaven is for Real. There are many others. Recently the Evangelical Christian Publishers Association honored Dr. Mary Neal’s To Heaven and Back for selling more than one million copies.
