I'm interested in reading the book Heaven is For Real. It's based on a true story of a boy undergoing surgery and was able to meet Jesus and people in his family who had passed away that he wasn't told about in addition to describing what his parents were doing while he was undergoing surgery where he was under anesthesia. Anyways, I'm a Christian but I'm trying to understand how someone can be able to see God, Heaven, etc and still be able to be alive here on Earth. I'm trying to grasp how that can happen to some people and not everyone be able to go there and come back. I'm looking for other Christian's perspectives so if you're not a Christian then no need to reply! Thanks.
