hmmm, I think a book that had unique never before seen text that would change automatically so it could be read be any living person would be worthy of God. Let it be bound by organic material that has not been around on Earth for at least 10,000 years and have a burnt image of God's face on the inside cover. That should about do it. Oh wait, seeing how some church would probably hide it away for nobody to see, I'd add that every time it was hidden away, it would duplicate itself and project the new copy of itself to a completely different place in the world for someone else to possess it and share it. For God, easy.
WWooowww that was quite a request,
For, in accordance with the purpose of the examinations and trials that man
is to undergo, the way must be shown to him without depriving him of his
free will: the door of the INTELLIGENCE must remain open, and its freedom
MUST NOT be snatched from its hand. But if miracles had occurred in SO
APPARENT a way, intelligence would of had no choice; Charles Manson or
Hitler would have believed and behaved like mother Teresa, or the companions
of the prophets, Coal would have had the value of Diamonds, and no
purpose would have remained for testing and accountability.:shout
