QUOTE : Inoculation introduces a mild form of a disease into a body, thereby stimulating the growth of antibodies and rendering the person immune to getting a full-blown version of the sickness. In the same way, post-Christian society contains unique resistance and "antibodies" against full-blown Christianity. For example, the memory of sustained injustices that flourished under more Christianized Western societies has become an antibody against the gospel. Christianity was big back when blacks had to sit on the back of the bus and when women were beaten up by men without consequences. We've tried out a Christian society and it wasn't so hot. Been there. Done that. In a society like ours, most people only know of either a very mild, nominal Christianity or a separatist, legalistic Christianity. Neither of these is, may we say, "the real thing." But exposure to them creates spiritual antibodies, as it were, making the listener extremely resistant to the gospel. These antibodies are now everywhere in our society.
