Christmas is about the creator of universe, God almighty himself, breaking into humanity. Yahweh becoming human.
Who was ready for Yahweh to come?
No one in Bethlehem. They did not even care enough to make room for a woman about to give birth.
There were some who were ready. The shepherds, the wise men, Simenon Anna. Even Herod (though he tried to kill Yahweh).
Where was everyone else? The priests?
Yahweh faced rejection the moment he entered the world as a baby.
But he still entered into the muck of this world.
And the miracle is that Yahweh still breaks into this world, still enters into the muck.
Are we ready?
"Here I am! I stand at the door and knock. If anyone hears my voice and opens the door, I will come in and eat with that person, and they with me."
Revelation 3:20
