Faith means lots of things to me. And none are easy to explain.

I have faith in people--to do what's right and occasionally what's wrong. I have faith in my students to be honest with me, and occasionally not. I have faith in God, and occasionally I lose that faith. I have faith in love--that it will be true and sometimes not.
I have faith the sun will rise tomorrow, and I have faith that the day will come when I won't see it. I have faith that the men and women I enter fires with will look out for me and me for them. I have faith that I will do my best to be a good person, and I have faith that I will not always achieve that goal. I have faith that some people will like what I wrote, and I have faith that some won't. Faith is maybe what we know to be true tinged with lots of hope.
