Anne Graham Lotz Updates Book on Heaven

The daughter of famed evangelist Billy Graham has updated her book on heaven.

Anne Graham Lotz said her 95-year-old dad's age and her husband's failing health moved her to revise and re-release the 2001 book Heaven: My Father's House.

The book's title has a double meaning. It refers to her childhood home as the daughter of Billy Graham and also to Jesus' description of heaven in scripture.

Lotz noted her father hasn't had any recent medical crisis and that he remains alert, especially when she reads scripture to him.
