It was the voice of a hundred other Christmas sermons I've heard. You know the part where you're meant to challenge the saccharine sweet domestication of Jesus with an embarassed: "But of course the baby in the manger grew up. We mustn't leave Jesus in the crib! He's a full grown man now you know! Don't look down on Jesus."
It's the attempt to wake people up from their preconceptions and show them something surprising. But you know the way to really shock people. Dwell on the manger. Make a determined effort to look down on Jesus. And proclaim that here - right here - is the true and living God. That'll wake em up from their preconceptions.
