Do miracles really happen? Can we know if the supernatural world exists? "The central miracle asserted by Christians is the Incarnation. They say that God became Man. Every other miracle prepares the way for this, or results from this." In Miracles, C. S. Lewis takes this key idea and shows that a Christian must not only accept but rejoice in miracles as a testimony of the unique personal involvement of God in creation. Using his characteristic warmth, lucidity, and wit, Lewis challenges the rationalists and cynics who are mired in their lack of imagination and provides a poetic and joyous affirmation that miracles really do occur in everyday lives.
