" I am grateful, too, to Lewis for having the courage to yell, to doubt, to kick at God with angry violence. This is part of a healthy grief not often encouraged. It is helpful indeed that C.S. Lewis, who has been such a successful apologist for Christianity, should have the courage to admit doubt about what he has so superbly proclaimed. It gives us permission to admit our own doubts, our own angers and anguishes, and to know that they are part of the soul's growth. "

― Madeleine L'Engle , A Grief Observed
