Why logical arguments for Messengers don't work.

[Mystic]

Mystic, you seem to be suggesting that the apparent perfection of a particular artifact, in your example a book, can only be explained as Divine. For the sake of argument, I'll assume that the Koran is the best example of poetic expression in all of human history. From my perspective many of the greatest human achievements seem incredible such as, the Sistine Chapel, the collected works of Shakespeare, the music of J. S. Bach and Mozart. Yet each of these is a testament to the amazing capacities of truly remarkable people.

No you misunderstood the argument. I was suggesting in the beginning that perhaps revelations no matter how great cannot be recognized to be divine. However, I showed if this was the case, and the arguments that God would send Messengers or appoint Guides still holds true, then he can have a Guide in each present among the people performing miracles. In other words it's not necessary rationally that God does this by an lasting revelation. However observation shows that God didn't do this. However if we assume (1) God exists (2) he has good reasons to send guidance in form of appointed authorities and guides he chooses if and only if he can prove such guidance..then it follows that there is a way to recognize a writing is God's and beyond human capability. And given that is true, the only religion emphasizing on this would stand to reason, to be true religion. If we assume (1) God exists (2) he has good reasons to send guidance in form of appointed authorities and guides if and only if he can prove such guidance and authority on their part.

If there is no everlasting book that we can see is from God and not from humans and their capability, then it would stand to reason God would in this day and age, and through out the years, have an apparent guide performing miracles to prove his authority.
