Native North Carolinian Eben Alexander is the author of the best-selling "Proof of Heaven: A Neurosurgeon's Journey into the Afterlife." The book describes his 2008 near-death experience and asserts that science can and will determine that heaven really does exist. Dr. Alexander visited Christ Church just as his book was topping the best-seller list. Over a thousand people filled All Saints' Hall and the Gallery to hear Dr. Alexander talk with The Reverend Chip Edens.
