The Bible would be for me a source of information.
True religion comes out of yourself, it comes on a moment when you find in yourself the need to believe in the existence of a higher creature. The bible may help you in providing the information of all the good things that creature and his messias Jesus stand for.
That GFR thing wasn't well chosen, cancell that part of mine.
That would be like being a Muslim and not believing in the Koran.
Or a Jew not believing in the Thora.
