Faith is an openness to the unknown. It is the willingness to walk in the darkness, to proceed in life without certainty. Faith does not preclude fear, it enables us to act in the face of fear. It is not the opposite of doubt; rather it invites us to entertain and examine all that appears inconsistent with our inherited beliefs. Faith is not an unwavering adherence to a way of life, but a radical interfacing with the unpredictable changes and chances of life itself, and with the commitments we make along life's way.
(Frank Stella from "A Faith Worth Believing.)
