I'm only saying that Paul's letters and story are part of the bible, and I don't see why they wouldn't be as reliable to you as anything else in the bible.
Big difference there.
The Bible is reliable to the degree the men who were inspired succeeded in hearing the Lord. The Koran, on the other hand, is made up of bits and pieces of erroneous history, and at its root it seems to be primary composed of a Syrian Orthodox missionary's manual used to Christian the Arabs in Mecca.
There's some other stuff in there from old Torahs found in the desert.
So, which would you rather have ~ the Inspired Word of God, or a Xerox copy of the Koran?
I think the choice is easy.
