Jo, You might want to look at the archives of a blog called Daas Hedyot.( http://daashedyot.blogspot.com/) The author grew up in a very Orthodox Jewish environment, and if you go back far enough in the archives you'll find several posts where he describes what he went through as a Yeshiva (rabbinical school) student as his beliefs started to unfold. Some of it probably won't carry over to a Christian, but there might be a lot that does carry over.
