The Apostle Paul transitions from his discussion about the Jews being placed on the back burner in God's salvific plan to practical discussions in the rest of the Book of Romans about how Christians are to think and live. He begins by looking at the sacrificial lives of the Christians versus the schematized world of unbelief. Too many Christians have yielded to the nonsense of the secular world that Christianity is not something to be personally contemplated; that a great gulf is fixed between faith and "science," which can never be bridged. That, though, is not what Paul argues in Romans 12:1-2. He points out that Christianity is not only a thoughtful faith, but completely logical and reasonable, with the starting point in the will of God, as opposed to the world, which ultimately resides in fallen humanity.
