Faith can operate on low levels such as: You arrange to meet with a friend at the park tomorrow.
You don't know for a fact that you will still be alive, or that your friend will, or that an accident won't befall either of you, etc. You operate on faith that your and their word will be made reality.
This is faith. It doesn't need to involve god, it doesn't have anything to do with superstition. You just take a belief and you act as if it will pan out.
