For me, a faith issue is one thing, and a faith despite reason issue if something else.
I believe in air, because I see that my breath can fill a balloon, I believe that air contains oxygen, since things rust when left in air. Because what I can see and feel makes sense, then having faith in the scientific description of air, that it is composed of nitrogen, oxygen, Co2 and various traces gases is pretty easy. The same is true of gravity.
On the other hand, believing in angels, believing that for several thousand years there was a God, and at some inexplicable date in history, God decided to send a previously unmentioned son to walk about for 32 years in an unremarkable way and then to spend a year of so gathering followers and getting himself crucified so that I and everyone after that date would be saved from their sins so that we all could sing in the Choir Celestial instead of frying in Hell where we actually belonged...
Well, there is no reason that can make sense of that for me.
There are many, many, many things in the Bible that lead me to conclude that this was not written by anyone guided by any logical force. It appears to me to have been written entirely by men who had a very limited knowledge of the world, who incorporated a bunch of typical folk myths into a rather random set of documents, some of which are words of wisdom, others are wacko rantings and others are folktales.
It seems highly unlikely to me that any sane omnipotent, omniscient being could have presided over all this, and if he had, then why do further "improved' religions keep popping up, like Islam, Mormonism, and such?
It might seem somewhat sane to assume that it all was created by some force, but it seems far less logical that it was created by the God mentioned in the Bible.
