Definition of faith

In my English class, the teacher said that we can't use source materials that are intended to be accepted on faith (such as the bible). But I thought, can't we defend the bible with archeological evidence? People seem to assume that when it comes to religion, science is put to the side and we use faith. With that premise they can easily disregard religion. I would too.

What if we redefine faith? Faith isn't holding onto a belief against all evidence, faith is holding onto one true thing, backed up by logic and evidence, when all appearances contradict. It's like parachute jumping. All the wind, roar, and dreadful empty air around you says you're going to die if you jump, but that true parachute on your back tells you for certain that you'll make it.

So you jump.
