madeleine l'engle, on "faith"

"if faith never encounters doubt,
if truth never struggles with error,
if good never battles with evil...
then how can faith know its own power?

in my own pilgrimage,
if i have to choose between a faith that has stared doubt in the eye and made it blink,
or a naive faith that has never known the firing squad of doubt,
i will choose the former every time."
