And the angel said to them, “Fear not, for behold, I bring you good news of great joy that will be for all the people. For unto you is born this day in the city of David a Savior, who is Christ the Lord.” (Luke 2:10-11, ESV)

XMAS Day
by G. K. Chesterton

Good news: but if you ask me what it is, I know not;
It is a track of feet in the snow,
It is a lantern showing a path,
It is a door set open.
