I don't normally just link to other blogs' posts, but this is just so well put that I when I saw it a couple of weeks ago I saved it for today. It's one of those things that I wish I'd written myself: "The Historicity of the Resurrection of Christ" by Mark Musser. Basically, the way I usually put it to my students, "The life of Jesus is better documented with earlier, more reliable sources than is the life of Julius Caesar." It's well worth reading. Happy Easter!
