Gerard Manely Hopkins has a short Christmas poem I love.
Moonless darkness stands between.
Past, the Past, no more be seen!
But the Bethlehem-star may lead me
To the sight of Him Who freed me
From the self that I have been.
Make me pure, Lord: Thou art holy;
Make me meek, Lord: Thou wert lowly;
Now beginning, and alway:
Now begin, on Christmas day.
