Evangelicals sometimes expect too much or, to put it more precisely, we look for a kind of change God hasn't promised. It's possible to expect too little, but under-expectation is usually a cynical reaction to dashed hopes for too much. We manage to interpret biblical teaching to support our longing for perfection. As a result, we measure our progress by standards we will never meet until heaven.
A spirit of license makes a man refuse to commit himself to any standards. The right time is the way he sets his watch. The yardstick has the number of inches that he wills it to have. Liberty becomes license, and unbounded license leads to unbounded tyranny. When society reaches this stage, and there is no standard of right and wrong outside of the individual himself, then the individual is defenseless against the onslaught of cruder and more violent men who proclaim their own subjective sense of values. Once my idea of morality is just as good as your idea of morality, then the morality that is going to prevail is the morality that is stronger.
My theory on literature is an author who does not indulge in trashiness-writes about people you could introduce into your own home.. He did not care to read a book or go to a play about people he would not care to meet at his own dinner table. I believe we should live by certain standards and ideals..
