I have mixed feelings about this one. It's been mega popular since it came out, so I had this idea that it offered more proof that Heaven exists. I don't really need proof, but I was curious. I didn't get the impression that any new evidence was offered, so that left me feeling disappointed.
A little boy, barely 4 years old, experiences health issues and needs surgery and during surgery he said he went to Heaven and came back. He tells his parents what he experienced and they're questioning whether he truly experienced this. His father is a pastor at a church, so he's able to connect his son's experiences with scripture. The boy's descriptions of Heaven are typical - bright colors, nobody is old, God has a throne, etc. The boy said he met his sister in Heaven and asked his mother if she lost a baby. She's surprised by the question, because they never told him about it, but she tells him yes. The boy is also able to identify his grandfather in an old photo. I don't consider any of these facts as evidence that it happened, but it was still an interesting story.
The storytelling is basic, nothing spectacular. At times, the father's reactions to his son's comments sound exaggerated. The father would say something like, "I was floored" or "I was stunned," but the situations didn't justify it.
I don't want to be a skeptic or question whether somebody really experienced what happened in this book or if they made it up. The boy survived a surgery that he wasn't expected to survive so maybe that's all of the evidence that we need. I wouldn't put this at the top of your list, but it's still worth reading.
