Frederick Buechner in his book, Telling the Truth: The Gospel as Tragedy, Comedy, and Fairy Tale, explains:
The Gospel is bad news before it is good news. It is the news that man is a sinner, to use the old word, that he is evil in the imagination of his heart, that when he looks in the mirror all in a lather what he sees is at least eight parts chicken, phony, slob. That is the tragedy. But it is also the news that he is loved anyway, cherished, forgiven, bleeding, to be sure, but also bled for. That is the comedy. And yet, so what? So what if even in his sin the slob is loved and forgiven when the very mark and substance of his sin and of his slobbery is that he keeps turning down the love and forgiveness because he either doesn’t believe them or doesn’t want them or just doesn’t give a damn? In answer, the news of the Gospel is that extraordinary things happen to him just as in the fairy tales extraordinary things happen.
