It was pretty good--no stunning revelations, for me anyway, though. I can't say it made me think of Christmas differently, but I can see how it would do that for some people. Anyway, if you're looking for a slightly different way to view the story and its purpose, here's one. I like their exposition of the birth narratives as parables or overtures--probably because it's similar to how I teach about the Christmas stories! :-)
Now on to fluff for the holidays--lots of travel coming up, so I should be able to finish a couple more books before the end of the year!
