Ok...so a lot of things make me think of U2 songs: reading Mary's story, and her daring song of celebration in Luke's gospel strikes me as more than a bit like "Peace on Earth":
Jesus, in the song you wrote/the words are stick in my throat: Peace on Earth.
We hear it every Christmas time/but hope and history won't rhyme, so what's it worth: Peace on earth.
Her song is a wild promise--so complete that it may seem like pure fantasy. God's promise has been fulfilled.
Mary dares to sing a song of celebration. She sings about the work already DONE in God--even as she's just pregnant with Jesus. An unwed mother, destined to be talked about by others, who's gonna have to lay in a manger after he's born, because there won't be any room in the inn--she sings about the work already DONE. (Past tense!)
I wonder what amazing sings of God's reality are all around us--promise as wild as incarnation--but unnoticed or not believed by the rest of us.
I wanna sing like Mary.
And then I wanna live like it's true.
