text: In  Paul addresses the faithfulness of God to the Israelites, where he says that God has been faithful to his promise. Paul hopes that all Israelites will come to realize the truth, stating that "Not as though the word of God hath taken none effect. For they are not all Israel, which are of Israel: Neither, because they are the seed of Abraham, are they all children: but, In Isaac shall thy seed be called." Paul affirms that he himself is also an Israelite, and had in the past been a persecutor of Early Christians. In  Paul talks about how the nation of Israel has not been cast away, and the conditions under which Israel will be God's chosen nation again: when Israel returns to its faith, sets aside its unbelief.
  Transformation of believers (12–15:13)
  From chapter 12 through the first part of chapter 15, Paul outlines how the gospel transforms believers and the behaviour that results from such a transformation. This transformation is described as a "renewing of your mind" (12:2), a transformation that Douglas J. Moo characterizes as "the heart of the matter." It is a transformation so radical that it amounts to "a transfiguration of your brain," a "metanoia", a "mental revolution."
