The world misses the lesson because it confuses littleness with weakness, child-likeness with childishness, and humility with an inferiority complex.
It forgets that great moral strength may be hidden in physical weakness, as Omnipotence was wrapped in swaddling bands; and that great Wisdom may be found in simple faith as the Eternal Mind was found in the form of a Babe. There is strength – strength before which the angels trembled, strength before which the stars prostrated, and strength before which the very throne of Herod shook in fear.
“When you got what you wanted, were you happy? Do you remember when you were a child, how ardently you looked forward to Christmas? How happy you thought you would be, with your fill of cakes, your hands glutted with toys, and your eyes dancing with the lights on the tree! Christmas came, and after you had eaten your fill, blown out the last Christmas candle, and played till your toys no longer amused, you climbed into your bed and said, in your own little heart of hearts, that somehow or other it did not quite come up to your expectations. And have you not lived that experience over a thousand times since?” ~Fulton Sheen (You)
