This is by Leslie Leyland Fields:

“Let the stable still astonish:
Straw-dirt floor, dull eyes,
Dusty flanks of donkeys, oxen;
Crumbling, crooked walls;
No bed to carry that pain,
And then, the child–
Rag-wrapped, laid to cry
In a trough.
Who would have chosen this?
Who would have said,
“Yes,Let the God of Heaven and Earth
Be born in this place”?
Who but the same God
Who stands in the darker, fouler rooms
Of our hearts
And says,
‘Yes,Let the God of Heaven and Earth
Be born in this place.'”
