Once the gospel starts being presented primarily as that which brings such-and-such benefits, be they freedom from alcohol abuse or just emotional highs every once in a while, the distinctive particularity of Christianity is lost. Islam too gives people self-respect, cleans up neighbourhoods, gives a sense of purpose; self-help programs have brought many back from the brink of self-destruction to decent lives; and, while Christianity gives me a sense of meaning and worth, so, I believe, does ferret-breeding for some people. So what have I to say to the perfectly content ferret breeder? Not a lot, if Christianity is primarily about feelings, whether of satisfaction, happiness or otherwise. I have Jesus; they breed ferrets. Result in both cases: happiness. So what’s the difference? The difference, of course, lies not in the experienced effect but in the cosmic bottom-line: Christ is God acting to save for all eternity; ferrets are good only as temporary distractions from the deeper realities and concerns of life.
