Do you know who you hold, Mary? You secure the Author of grace. He who is ageless is now moments old. He who is limitless is now suckling your milk. He who strides upon the stars, now has legs too weak to walk; the hands which held the oceans are now an infant's fist. To Him who has never asked a question, you will teach the name of the wind. The Source of language will learn words from you. He who has never stumbled, you will carry. He who has never hungered, you will feed. The King of creation is in your arms.
What manner of love is this?
-- Max Lucado, from An Angel's Story: The First Christmas from Heaven's View
