I do agree it is impossible to say that this prophecy has been fulfilled in the best sense.
I understand your argumentation with regards;
To illistrate [sic] : I will go on record, right here, right now in predicting that this post will endure forever.
However, if in two thousand years a worldwide religion had spread based upon your post made on a backwater internet forum, I am sure some may start to claim divine inspiration on your behalf.
From my perspective, it seems the writers of the bible were essentially claiming their words would last forever. These books are some of humankind's first moral teachings, stories, philosophy, etc.. written down either created or borrowed from oral tradition. The claim they would endure into the world we know today and have the influence they do is quite remarkable; evidence for some of divine intervention, evidence of the power of memes for others, for me... suggestive that despite all our advances the human mind still lingers closely to that of our forebears that first walked upright.
Again, I do understand that the prophecy does not fit exactly into the crtieria required. However, I think it could hit the 'special' knowledge requirement - there were many religious views around at the time, who could have known that this tiny religion would grow to dominate the western world and still be going strong in 2014!? I do understand your point re the quote above - but I am playing advocate.
