To reach people in our day, the gospel will have to be distinguished from moralism, because moralism is what most people outside the church think Christianity is all about – rules and standards and behavior and cleaning yourself up.  Millions of people, both inside and outside the church, believe that the essential message of Christianity is: “If you behave, then you belong.”  From a human standpoint, that’s why most people reject Christianity.
