Abstract
At the very heart of historic Christianity is a truly astounding truth-claim that is celebrated all around the world at Christmas. This central article of the Christian faith is known as the doctrine of the Incarnation: God became man in Jesus of Nazareth. It is this truth that sets Christianity apart from all other religions of the world (including Judaism and Islam). For it is unique to Christianity to discover a God who takes the initiative in becoming flesh in order to redeem sinful human beings. As C.S. Lewis aptly put it, "The Son of God became a man to enable men to become sons of God."
