Here is a great quote by Bavinck on the incarnation, one that is fitting for this Advent season. You can find the whole thing over at the RTS Washington site.
The incarnation of God is the central fact in special revelation, the fact that sheds light upon its whole domain. Already in creation God made himself like human beings when he created them in his image. But in re-creation he became human and entered totally into our nature and situation. In a sense God’s becoming human starts already immediately after the fall, inasmuch in his special revelation God reached back deeply into the life of the creation, linked up with the work of his own providence, and so ordered and led persons, situations, and events, indeed the entire history of a people, that he gradually came close to the human race and become ever more clearly knowable to it. But it reaches its culmination only in the person of Christ, who therefore constitutes the central content of the whole of special revelation.
