Christianity was originally never understood as a set of teachings that one took on. Christianity was a power that took you up. It completely turned you inside out, transformed you from the inside.  The classic example is the conversion of Paul. Paul was an abusive, violent zealot. He went from someone who was deeply unhappy and restless to someone who was utterly unflappable, absolutely content. How? A radical, deep conversion.  We all need to know how to live deeply converted lives. And though Paul’s conversion is dramatic, it shows three things involved in every conversion: 1) an untame God, 2) a stubborn fact, and 3) a radical relationship.
