It's a surprisingly tricky question!
We were having a discussion about religion at Main Street Plaza (so what else is new?), and I noticed that different people were using very different definitions of the word "faith"!
I've found that a lot of unnecessary confusion and misunderstanding can result from assuming that everyone is using a word to mean the same thing when they're not. So I wrote a new post: What is Faith? to help each person clarify which definition(s) they're using -- with a fun list of twenty statements that may or may not be "faith"!
The answer sets we've gotten so far show a surprising variety in what people would call "faith". Try it yourself -- but be sure to write out your own answers before reading other people's.
I'm not claiming that one set of responses is necessarily right -- I'm just curious to see the range of opinions! :D
