Faith or magick....

I wonder soemtimes about the words that Christians use and there understanding of them. On Saturday I was talking with soemone who used the term that is not having enough faith, but the way she used it was like faith was a type of magick - that if you say the right incantation then you will be protected.
I say it worries me becuase that is not how i have ever understood faith, reliance on God yes but protection from harm - well deffinatly not always. It doesn't line up with scritpure either - the book of Job certainly doesn't fit with it. In fact I think one of the reasosn we have Job in the bible is to counter act an argument that associates faith with always being protected.
I always explain to people that faith is what keeps you going between one expereince of God and another. I think my understanding seem to be closer to the witness of scripture - but hey i am always open for correction
