God is in the Manger: Reflections on Advent and Christmas

Dietrich Bonhoeffer wrote:

God travels wonderful ways with human beings, but he does not comply with the views and opinions of people. God does not go the way that people want to prescribe for him; rather, his way is beyond all comprehension, free and self-determined beyond all proof.

Where reason is indignant, where our nature rebels, where our piety anxiously keeps us away: that is precisely where God loves to be. There he confounds the reason of the reasonable; there he aggravates our nature, our piety—that is where he wants to be, and no one can keep him from it. Only the humble believe him and rejoice that God is so free and so marvelous that he does wonders where people despair, that he takes what is little and lowly and makes it marvelous. And that is the wonder of all wonders, that God loves the lowly.… God is not ashamed of the lowliness of human beings. God marches right in. He chooses people as his instruments and performs his wonders where one would least expect them. God is near to lowliness; he loves the lost, the neglected, the unseemly, the excluded, the weak and broken.

Dietrich Bonhoeffer
That … is the unrecognized mystery of this world: Jesus Christ. That this Jesus of Nazareth, the carpenter, was himself the Lord of glory: that was the mystery of God. It was a mystery because God became poor, low, lowly, and weak out of love for humankind, because God became a human being like us, so that we would become divine, and because he came to us so that we would come to him. God as the one who becomes low for our sakes, God in Jesus of Nazareth—that is the secret, hidden wisdom… that “no eye has seen nor ear heard nor the human heart conceived” (1 Cor. 2:9).… That is the depth of the Deity, whom we worship as mystery and comprehend as mystery.
