Why is faith important?

[Drich]

Once you have it, then what? Are you one that constantly needs to be reassured? Do you keep a hammer and a feather on your night stand to test and see if Graveity still works before you get out of bed every morning?

Or once that it has been established the need for constant evidence,testing and proof gets tossed aside because now you know what to look for to know that it is working?

We're getting into the murky distinction between reasonable expectations, such as gravity, the sun rising, my body being hungry later, and faith, believing in something without evidence.
I've seen multiple points of evidence for the effects of gravity, the sun rising, my body getting hungry, but I've seen nothing that indicates a god. I'm not going to start off believing something before its proven. That's called gullibility.

What if it were up to you to prove it? Would you make the effort?
