The truth is that Christians affirm the incarnation because they have to—it defines Christianity. Genesis 6:1–4 is set aside as peripheral. But belief in a personal God as the Bible describes means embracing the supernatural. For the Christian, the high point of the supernatural story of Scripture—its most dramatic and unthinkable expression—is the incarnation of God in Christ. The notion that the sons of God came to earth in fleshly form ought to be more palatable than the incarnation, since it is less supernaturally spectacular.
