Ed Clowney points out that if we ever tell a particular Bible story without putting it into the overall main Bible story (about Christ), we actually change the meaning of the particular event for us. It becomes a moralistic exhortation to 'try harder' rather than a call to live by faith in the work of Christ. There is, in the end, only two ways to read the Bible: is it basically about me or basically about Jesus? In other words, is it basically about what I must do, or basically about what he has done? Example: If I read David and Goliath as basically giving me an example, then the story is really about me. I must summons up the faith and courage to fight the giants in my life. But if I read David and Goliath as basically showing me salvation through Jesus, then the story is really about him. Until I see that Jesus fought the real giants (sin, law, death) for me, I will never have the courage to be able to fight ordinary giants in life (suffering, disappointment, failure, criticism, hardship). The Bible is not a collection of "Aesop's Fables", it is not a book of virtues. It is a story about how God saves us. Any exposition of a text that does not 'get to Christ' but just 'explains Biblical principles' will be a 'synagogue sermon' that merely exhorts people to exert their wills to live according to a particular pattern. Instead of the life-giving gospel, the sermon offers just one more ethical paradigm to crush the listeners.
