The Angels of Advent are saying, "Do not be afraid" -- we bring good news of immigration reform.
And what does fear do to us?
We disregard the good news at our doorstep, the opportunity to live with Jesus among us, and keep on building walls at our threshold. Perhaps that's why the angels of the Bible repeat this admonishment -- Do not be afraid -- over and over again, for fear inhibits our ability to see and hear a new vision.
I remember as a child wanting to leave the lights on in my room at night. The shadows and sounds were too much for an imagination that could run wild to handle. As adults, of course, it's our duty to assure children that nothing is living in their closets or under their beds. We offer the comfort of reality so that the child will go to sleep and have sweet dreams.
But you have to admit, as adults we are gripped by the same fear but on a different level. We may compulsively check to make sure the front door is locked. We don't look strangers in the eye (especially those we deem to look "strange") as we pass them on the street.
