Faith is...

Probably one of the most unpleasant things I do when I can no longer bear the guilt of putting it off is going to the dentist to have my teeth cleaned. Can't stand it!
However at my recent cleaning I read the following quote the Dr. had framed on the wall:
"Faith is not belief without evidence
But rather, trust without reservation"
This statement seems to me to take faith from the science/religion battlefront where all too often we ardently debate creation and evolution and other such 'hot topics' and, instead, nudges us to the heart of religion - a personal relationship. How much do we really trust God?
