Weeell you might want to check out some of the criticisms of his story ...
How does one know when they have had a real encounter? Are you saying that Eben was not enthused enough? Based on the almost 6,000 reviews on Amazon, the jury is still out. His past thoughts and recent illness point to his epiphany of God that seemingly didn't exist before. As I said, I'm not 100 percent sure he believes what happened to him is real. How can one find the answer? Does God himself have to appear before we postulate the answer? There is no way to find the answer, but I don't think his thoughts are flapdoodle.ricksreviews.blogspot.com
I'm also not aware of an religious system in the world in which God proves Himself to any one. I'm open to correction on this but religion is generally based on faith and faith, in all definitions I'm familiar with, is belief in the unseen. Now if God was going to show up on some one's almost death bed and send them back with some kind of esoteric message, one has to ask why He just doesn't do that for every one and solve this whole doubt issue once and for all. Because He clearly doesn't do that, and how all the major and most of the minor belief systems I'm familiar with require some version of faith, for me it kind of brings the entire notion of these experiences being genuine into question.
I would have to disagree Meadow. God, in the Bible generally appeared in a personal manner to a very select few. Personal communication (like speaking to Elijah in a still, small voice) is different than signs and wonders (allowing Elijah to call down fire from heaven onto the altar in the presence of the nation of Israel). Why would God operate differently now? He spoke to Moses privately and commanded Moses to take the message out into the world. The people had a choice to believe the message or not. Of course Moses message was backed up by signs and wonders. However, God commanded Jonah to go and tell Nineveh to repent. They listened to him without the benefit of signs and wonders to bolster their trust.
So people may react differently to a message from God, but God typically delivers the message in the same manner. He picks one, or a small group and communicates His wishes. Then they go out and spread the word.
Regarding earning profit from the message, it is questionable. I would tend to agree that that might be a pretty big obstacle to believing a story like this. It is not really mentioned whether the prophets had money. Most of them seemed to live pretty meager lives, often depending on God for basic life requirements like food and shelter.
