Faith is not a thing that comes into being out of nothing. It originates in an event. In the spiritual vacancy of life something may suddenly occur that is like the lifting of a veil at the horizon of knowledge. A simple episode may open sight of the eternal. A shift of conceptions, boisterous like a tempest of soft as a breeze may swerve a mind for an instant or forever. For God is not wholly silent and man is not always deaf. God's willingness to call men to His service and man's responsiveness to the divine indications in things and events are for faith what sun and soil are for the plant.
