Bookstores abound with Christian self-help books, novels, movies, and introductions to a dizzying array of Xtrian-oriented subjects. But what happens when, after years of being a serious Xtrian, you already know all this stuff? You want something that's deep, anotherwords a real challenge, but where do you go to get it?
The answer is the higher education system. Christian professors, either those working for Xtrian schools or otherwise, are duty bound to constantly be spewing out well written theological dissertation after another. Sadly, these hard won copies of intellectual gold often go unnoticed. I's a real tragedy.
So be smart! Shop around the online bookstore of your local Christian college and get a list of textbooks from the local university's class on Christian history!
