" metaphor means “to see as.” Metaphorical language is a way of seeing. To apply this to the Bible: the Bible not only includes metaphorical language and metaphorical narratives, but may itself be thought of as a “giant” metaphor. The Bible as metaphor is a way of seeing the whole: a way of seeing God, ourselves, the divine-human relationship, and the divine-world relationship. And the point is not to “believe” in a metaphor—but to “see” with it. Thus the point is not to believe in the Bible—but to see our lives with God through it. "
