Faith is better understood as a verb than as a noun, as a process than as a possession. It is an on-again-off-again rather than once-and-for-all. Faith is not being sure where you're going but going anyway. A journey without maps. Tillich says that doubt isn't the opposite of faith; it is an element of faith.
Each one of us could describe his or her life as a sacred journey. You are journeying from the beginning to the end, and what makes it sacred is that in the process of this journey you encounter the holy in various forms which, unless you have your eyes open, you might not even notice.
To journey for the sake of saving our own lives is little by little to cease to live in any sense that really matters, even to ourselves, because it is only by journeying for the world's sake - even when the world bores and sickens and scares you half to death - that little by little we start to come alive.
Listen. Your life is happening. You are happening. Think back on your journey. The music of your life.
