Faith is really quite simple. You say you are going to do something, and then you keep your word. Any man with integrity knows that this is how one lives honestly and truthfully.
So it is no mystery when faith works. It is the only thing that could happen, given where you started and where you ended. It is what occurs when hopes become words kept and a life lived.
It's something that can never be taken away, only given up.
Somehow, there's a certain freedom in it. You didn't see, but then suddenly it's there, and so you hold on to it.
And the light persists.
