Just a heads up, but Ehrman is actually one of the most questionable NT scholars out there and is an apostate at this point. Any major theological scholar will warn you about him. I'd recommend any number of scholars over him. You can find a number of critiques of his work from the best names in biblical scholarship. Be very wary of him. At this point, I believe he is simply a tool the devil is using to get people to question their faith. Example of a response to Ehrman's scholarship:

How God Became Jesus

The Real Origins of Belief in Jesus' Divine Nature---A Response to Bart D. Ehrman

Didn't intend to comment, but appreciated your original post and couldn't let this suggestion pass un-contested.
