[Many Christians find the Christian Bible, comprised of the Old and New Testament, diffuse, lacking unity, and therefore difficult to use in systematic theology. Yet the Bible itself uses a powerful organizing principle that spans both testaments and unites them, namely the Exodus in its dual aspects of liberation and formation. There are three Exodus moments. Exodus I is the thirteenth-century B.C.E. foundational event. Exodus II is its sixth-century renewal. Exodus III is the first-century C.E. climactic renewal of Israel by Jesus.]
