Your notion of "non corruptible" does not mean "true"
A liar can write a thousand words, and they be preserved, lies and all, in writing for 1500 years.
It's not "truth" just because it was left intact.
And remind me again, what in the Bible teaches me that God is not God? What in the Bible teaches me that there is more than one god?
I can't seem to FIND that.
Well, that's the whole thing. Seems like God learns from his mistakes and finally got it right with the Quran where he finally learned how to make a non corruptible scripture. Muhammad never thought things out very much when he invented his claims.
