“The crucial significance of the cradle at Bethlehem lies in its place in the sequence of steps down that led the Son of God to the cross of Calvary, and we do not understand it till we see it in this context. The key text in the New Testament for interpreting the Incarnation is not, therefore, the bare statement in John 1:14, ‘The Word became flesh and made his dwelling among us,’ but rather the more comprehensive statement of 2 Corinthians 8:9, ‘You know the grace of our Lord Jesus Christ, that though he was rich, yet for your sakes he became poor, so that you through his poverty might become rich.’ Here is stated not the fact of the Incarnation only, but also its meaning; the taking of manhood by the Son is set before us in a way which shows us how we should ever view it—not simply as a marvel of nature, but rather as a wonder of grace.”
