I remember Paul Tillich, the great theologian, defined faith as courage. That is just wonderful. He said that is what faith will look like when you see it. It will look like courage. What faith is, is acting on your trust that God is faithful. Most of the time, if you are doing anything worthwhile, it is done on faith, and it takes courage.
Most people think the opposite of faith is doubt. They think, "I have some doubts, therefore I don't have faith." Well faith doesn't remove doubt. Faith is courage to go into an unknown future in spite of the doubts. Faith doesn't remove fear either. Faith is the courage to do the right thing even when your knees are trembling. Faith doesn't remove disappointments, or guarantee victory. Faith is the courage to keep on going even when you want to give up, but you keep on going.
That is what faith looks like. Madeleine L'Engel put it perfectly. "I don't have to have some special qualification to do what I have to do. All I have to do is have the courage to go on and do it."
