Interesting. I am also not a "person of faith", but I don't use that definition of faith. Most people I've known who value faith, do so in areas where they are not sure one way or another. Generally speaking, faith is something that provides comfort because it gives them certainty for things that are uncertain to the person -- especially for things that can not be proved or disproven. Sometimes I've seen people have a "crisis in faith" because they discover that something they believed to be uncertain (and hence a good candidate for faith based belief) turns out to be quite certain and not what they believe. Usually this is quite uncomfortable for them. Sometimes they are able to continue with their faith by shifting their interpretation of the thing they believe onto something that is still uncertain to them. Sometimes they struggle to find something that will throw doubt on the situation so that they can continue their faith. Sometimes they they abandon their faith. I've really yet to meet anyone who walks into walls because they have faith that they don't exist (or other equivalent situations). I'm absolutely sure that they exist, but I don't think they are very common to be honest.
