To start as any good apologist should I would like to point out, you failed to ackowledge any merit in my post and just flippantly brushed it off without consideration almost as if you are not really interested in exploring the possibilities, it seems you are just baiting to beat down posters.
Nice... ;)
So, playing my part, of course I didn't. I simply seek clarification on what you consider God's word.
You have slightly shifted the burden of proof with your question. If there is a prophecy that god's word is enduring, just because there are potentially false versions of biblical texts, if just one true version remains the prophecy would be still on track.
The burden always lies on the person making the claim. Hence the need for clarification on what you specifically mean by "God's word".
OneEyedJoe also made an excellent point, that something with no end date can't ever possibly be proved true.
