This may come as a surprise to you: Christianity is not an invitation to become a moral person. It is not a program for getting us in line or for reforming society. It has a powerful effect upon our lives, but when transformation comes, it is always the aftereffect of something else, something at the level of our hearts. At its core, Christianity begins with an invitation to desire. Look at the way Jesus relates to people. As he did with the fellow at the Sheep Gate (John 5), he is continually taking them into their hearts, to their deepest desires.
