From the beginning Christianity was certainly a life. But how was the life produced? It might conceivably have been produced by exhortation. That method had often been tried in the ancient world; in the Hellenistic age there were many wandering preachers who told men how they ought to live. But such exhortation proved to be powerless. Although the ideals of the Cynic and Stoic preachers were high, these preachers never succeeded in transforming society. The strange thing about Christianity was that it adopted an entirely different method. It transformed the lives of men not by appealing to the human will, but by telling a story; not by exhortation, but by the narration of an event. It is no wonder that such a method seemed strange. Could anything be more impractical than the attempt to influence conduct by rehearsing events concerning the death of a religious teacher? That is what Paul called ‘the foolishness of the message.’ It seemed foolish to the ancient world, and it seems foolish to liberal teachers today. But the strange thing is that it works. The effects of it appear even in this world. Where the most eloquent exhortation fails, the simple story of an event succeeds; the lives of men are transformed by a piece of news.”
