Paul declares that his heart's desire and prayer to God for Israel is that they be saved. He bears witness that they have a zeal for God, but not according to knowledge, for being ignorant of the righteousness of God and seeking to establish their own, they did not submit to God's righteousness. For Christ is the end of the law for righteousness to everyone who believes.
Moses describes the righteousness of the law: the one who does these things will live by them. But the righteousness of faith says there is no need to ascend to heaven to bring Christ down or descend into the deep to bring him up, for the word is near you, in your mouth and in your heart; that is the word of faith that is preached. If you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. With the heart one believes and is justified, and with the mouth one confesses and is saved. Scripture says that everyone who believes in him will not be put to shame. There is no distinction between Jew and Greek, for the same Lord is Lord of all, bestowing his riches on all who call on him; for everyone who calls on the name of the Lord will be saved.
Paul then poses a chain of questions: how can they call on one they have not believed in, believe without hearing, hear without a preacher, or preach unless sent? He quotes Isaiah about the beautiful feet of those who bring good news. But not all obeyed the gospel, and faith comes from hearing, and hearing through the word of Christ.
Finally he asks whether Israel has not heard, and answers that they did hear. He quotes Moses and Isaiah: God will make Israel jealous by those who are not a nation and will be found by those who did not seek him. But of Israel he says: all day long I have held out my hands to a disobedient and contrary people.
