The following is from George MacDonald's novel Adela Cathcart:
“The winter is the childhood of the year. Into this childhood of the year came the child Jesus; and into this childhood of the year must we all descend. It is as if God spoke to each of us according to our need: My son, my daughter, you are growing old and cunning; you must grow a child again, with my son, this blessed birth-time. You are growing old and selfish; you must become a child. You are growing old and careful; you must become a child. You are growing old and distrustful; you must become child. You are growing old and petty, and weak, and foolish; you must become a child—my child, like the baby there, that strong sunrise of faith and hope and love, lying in his mother’s arms in the stable.
“But one may say to me: ‘You are talking in a dream. The Son of God is a child no longer. He is the King of Heaven.’ True, my friends. But He who is the Unchangeable, could never become anything that He was not always, for that would be to change. He is as much a child now as ever he was. When he became a child, it was only to show us by itself, that we might understand it better, what he was always in his deepest nature. And when he was a child, he was not less the King of Heaven; for it is in virtue of his childhood, of his sonship, that he is Lord of Heaven and of Earth—‘for of such’—namely, of children—‘ is the kingdom of heaven.’ And, therefore, when we think of the baby now, it is still of the Son of man, of the King of men, that we think. And all the feelings that the thought of that babe can wake in us, are as true now as they were on that first Christmas day, when Mary covered from the cold his little naked feet, ere long to be washed with the tears of repentant women, and nailed by the hands of thoughtless men, who knew not what they did, to the cross of fainting, and desolation, and death.”
