quote AHB "That's interesting, JJ.  I have heard several doctors express faith in medicines, not because they believe they will work 100 times out of 100, but because they and others like them have experienced the efficacy of the stuff.  Furthermore, some even say that they don't know how or why they work, just that they have seen them do so.  Doesn't this sound remarkably similar to what many Christians - even non-Christian religious people say?"

Are we using the word faith in a loose way here?  It seems to me that what the doctors are using is their knowledge not their faith.

Like for example : I use washing up liquid and a mop to wash most of my dishes because I know it will shift most stuff.  If something is not shifted then I use a scrubber.
