Fear and Trembling Part 2
The second reading I've found about fear and God's coming. I'd usually skip over these, but this year they seem to belong here.

We have become so accustomed to the idea of divine love and of God’s coming at Christmas that we no longer feel the shiver of fear that God’s coming should arouse in us. We are indifferent to the message, taking only the pleasant and agreeable out of it and forgetting the serious aspect, that the God of the world draws near to the people of our little earth and lays claim to us. The coming of God is truly not only glad tidings, but first of all frightening news for everyone who has a conscience.

Only when we have felt the terror of the matter, can we recognize the incomparable kindness. God comes into the very midst of evil and of death, and judges the evil in us and in the world. And by judging us, God cleanses and sanctifies us, comes to us with grace and love. God makes us happy as only children can be happy.
