This time of year, I’m leaving work just about the same time the last light is failing. This is the pattern we live with in Minnesota, the pattern I grew up with. It’s woven in my DNA. This isn’t usually the coldest time of year (certainly not this year—the temperature is peaking around freezing, and we’re still snowless, though there are rumors of maybe a few flakes by Christmas). But it’s the time when the nights are longest. The time when the sun rations out tiny bowls of thin light-gruel to the orphans, and there’s little point in asking for more.

And that’s one reason I love Christmas. Because Christmas is the time when we defy that darkness. We burn up fuel that could be hoarded, feast on food that could be cached, and sing loudly that we believe in Light, and Light is coming back.

Sure, most of our customs have heathen origins. So what? I don’t care about the religion of the first man to trim a Yule tree any more than I care about the religion of the guy who built my house. If it’s a good house that keeps me warm in the winter and provides a place for me to gather with my family, that’s plenty for me.

I figure I know Odin and Thor as well as anybody, and they don’t scare me. Their bad elements don’t hurt me, and their good elements enrich my life. C. S. Lewis thought the old myths contained “good dreams” sent by God, stories that prepared heathens to recognize the gospel when it arrived.

I believe it.

I remember going out to do chores on the farm during Christmas season, when I was a boy. Was it cold? It was biting cold. It was burning cold. I pulled a ski mask over my face, and soon had a beard of ice forming around the mouth hole. It was dark out there—not city dark, where there are lights from house windows and street lamps to give relief, but country dark. Dark you could fall into and never hit bottom. Up above, the stars burned like an ammonia fire behind a moth-eaten blanket.

And as I trudged along, the snow squealing under my feet with a sound of tortured iron, I sang Christmas carols.

And that made the whole thing magic. That put me into a story, a pageant. It didn’t make the killer night warmer, but it made it beautiful. Deadly and beautiful, like a fine weapon.

A sword for the Lord.

Thank God for Christmas, I say.
