The fifth post in my series on Why Are There Differences in the Gospels? is up at What's Wrong With the World.
There will in all likelihood be a wrap-up post to follow, the last in the current series. That, of course, isn't to say that there won't ever be any other posts that discuss Licona's work, but that will be all in the current series.
If you know someone who is interested in this topic and who would profit from it, be sure to direct him to the Licona tags and New Testament tags both at W4 and here. Here are all of the Licona posts at W4, and here are all posts there tagged with New Testament. Here is the Licona tag at Extra thoughts, and here is the New Testament tag. There are a few unique posts here, though the majority of the recent posts are at W4.
