Three beautiful thoughts from Dietrich Bonhoeffer about the ways that God loves us and comes to us in Advent and Christmas:

Just when everything is bearing down on us to such an extent that we can scarcely withstand it, the Christmas message comes to tell us that all our ideas are wrong, and that what we take to be evil and dark is really good and light because it comes from God. Our eyes are at fault, that is all. God is in the manger, wealth in poverty, light in darkness, succor in abandonment. No evil can befall us; whatever men may do to us, they cannot but serve the God who is secretly revealed as love and rules the world and our lives...

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...

Jesus stands at the door knocking (Rev. 3:20). In total reality, he comes in the form of the beggar, of the dissolute human child in ragged clothes, asking for help. He confronts you in every person that you meet. As long as there are people, Christ will walk the earth as your neighbor, as the one through whom God calls you, speaks to you, makes demands on you. That is the great seriousness and great blessedness of the Advent message. Christ is standing at the door; he lives in the form of a human being among us.
