I can't wait to get the book! This near death experience the son had is one that I feel truly happened to this boy. You can probably read the Bible along side this book and it will confirm things mentioned there.
A person I know whose firefighter husband died putting out a fire in Syracuse, Ny years ago had a visitation from him about a year or so after his death.
He told her that Heaven is not a place where you sit around. There is much going on there. There is rest yet also much learning, much work inspired by love, much restoration plans, etc.
He mentioned about that too--about Christ coming to set up His Father's Kingdom on Earth eventually, and the need to allow God to prepare us for His coming.
