Of all the customs surrounding Christmas, it occurs to me the most singular, the most distinctive, is the custom of giving one another gifts. You realize how unique that is. There are other special occasions, birthdays, anniversaries, weddings, Father’s Days, Mother’s Days, and so on, in which somebody is given gifts. You bring your gifts to somebody, but the real question is … How many holidays do we have in which all of us give gifts to all of us? The answer is only one, and it’s right that we do it at Christmas because it highlights, it makes real, the central event, in some ways, the central truth of Christmas.
Jesus Christ came at Christmas, but he didn’t just come. He was given. ‘For unto us a child is born, unto us a Son is given …’ Jesus didn’t just come. He was a gift. That’s the central event of Christmas, and all the gift giving, in a sense, makes that real. Jesus was given. ‘For God so loved the world, that he gave his only begotten Son …’ Jesus did not just come. He was a gift.
There’s one place in which Paul is so overwhelmed by the thought of it that he breaks into praise, and he says, ‘Thanks be to God for his unspeakable gift,’ an unspeakable gift, an inexpressible gift. It’s beyond description. It’s beyond comprehension. Whenever Paul thinks about it, even for a while, his imagination and his heart explode.
