A New Kind of Man In his now classic book, Mere Christianity, C.S. Lewis writes:

"Niceness" - wholesome, integrated personality - is an excellent thing.  We must try by every medical, educational, economic, and political means in our power to produce a world where as many people as possible grow up "nice"; just as we must try to produce a world where all have plenty to eat.  But we must not suppose that even if we succeeded in making everyone nice we should have saved their souls.  A world of nice people, content in their own niceness, looking no further, turned away from God, would be just as desperately in need of salvation as a miserable world - and might even be more difficult to save.
