Gods forgiveness is worthless.

[Neo-Scholastic]

Personal revelation and experience is something particular only to you, and can't reasonably be countered against you by someone else, but at the same time can't be used as evidence for anyone else. That's all I'd say to that.

I remember reading much the same in Thomas Paine's "Common Sense". While I understand the sentiment, some consideration of the source may be appropriate. I have had my own personal spiritual experiences though I would not expect those to be believed except by those already inclined to do so. That said, I imagine the revelations to a random stranger would be much less authoritative to you than a famous scientist. For example, what if Stephen Hawking claimed to have received messages from angels or Daniel Dennett reported having an NDE. I imagine you would take their reported experiences more seriously. Of course, those two would probably dismiss them as fantasies, bits of undigested cheese, no matter how compelling the experience.
