"And while they were there, the time came for her to be delivered. And she gave birth to her first-born son and wrapped him in swaddling cloths, and laid him in a manger, because there was no room for them in the inn" (Lk 2:6f)
For the Saviour of the world, for him in whom all things were created, there was no room.
This should cause us to reflect - it points toward the reversal of values found in the figure of Jesus Christ and his message. From the moment of his birth, he belongs outside the realm of what is important and powerful in worldly terms. Yet it is this unimportant and powerless child that proves to be the truly powerful one, the one on whom ultimately everything depends.
So one aspect of becoming a Christian is having to leave behind what everyone else thinks and wants, the prevailing standards, in order to enter the light of the truth of our being, and aided by that light to find the right path
