Faith is better understood as a verb than as a noun, as a process than as a possession. It is 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 said that doubt isn't the opposite of faith; it is an element of faith.
