The real difficulty, the supreme mystery with which the gospel confronts us, does not lie in the Good Friday message of atonement, nor in the Easter message of resurrection, but in the Christmas message of Incarnation.
The really staggering Christian claim is that Jesus of Nazareth was God made man—that the second person of the Godhead became the ‘second man’ (1 Cor. 15:47), determining human destiny, the second representative head of the race, and that He took humanity without loss of deity, so that Jesus of Nazareth was as truly and fully divine as He was human.
‘The Word became flesh’ (John 1:14); God became man; the divine Son became a Jew; the Almighty appeared on earth as a helpless human baby, unable to do more than lie and stare and wriggle and make noises, needing to be fed and changed and taught to talk like any other child.
The more you think about it, the more staggering it gets. Nothing in fiction is so fantastic as is this truth of the Incarnation.
