The chess match recorded by Eisenbeiss actually happened, so it is true;
the questions were answered correctly, so that part is also true.
Finally, rebirth is a key message of spirituality and it is even in the Bible,
So that part of Eisenbeiss is also true.
What part is actually being questioned?
It seems to me that the source is giving us the truth every time.
Thus the source is not of importance; having an open mind for truth is what is important!

Please use own discernment; I have already referenced for you the "First Christians" audio so that you may follow up on the references/resources therein. I have also posted on the topic of rebirth in the Bible in this thread; I discern that you do not really understand where the Bible came from, nor are you even interested. You have no right to pound on my truth (you have no answer to the problem of the criterion, since you can't explain this presumed knowledge/criteria, you have a fatal flaw in your argument); judge not lest it be in ignorance!
