Romans 10:1-4
1 Brothers and sisters, my heart’s desire and prayer to God for the Israelites is that they may be saved. 2 For I can testify about them that they are zealous for God, but their zeal is not based on knowledge. 3 Since they did not know the righteousness of God and sought to establish their own, they did not submit to God’s righteousness. 4 Christ is the culmination of the law so that there may be righteousness for everyone who believes.
Romans 10:8-18
8 But what does it say? “The word is near you; it is in your mouth and in your heart,”[a] that is, the message concerning faith that we proclaim: 9 If you declare with your mouth, “Jesus is Lord,” and believe in your heart that God raised him from the dead, you will be saved. 10 For it is with your heart that you believe and are justified, and it is with your mouth that you profess your faith and are saved. 11 As Scripture says, “Anyone who believes in him will never be put to shame.”[b] 12 For there is no difference between Jew and Gentile—the same Lord is Lord of all and richly blesses all who call on him, 13 for, “Everyone who calls on the name of the Lord will be saved.”[c]
14 How, then, can they call on the one they have not believed in? And how can they believe in the one of whom they have not heard? And how can they hear without someone preaching to them? 15 And how can anyone preach unless they are sent? As it is written: “How beautiful are the feet of those who bring good news!”[d]
16 But not all the Israelites accepted the good news. For Isaiah says, “Lord, who has believed our message?”[e] 17 Consequently, faith comes from hearing the message, and the message is heard through the word about Christ. 18 But I ask: Did they not hear? Of course they did:
“Their voice has gone out into all the earth, their words to the ends of the world.”[f]
Romans 11:28-32
28 As far as the gospel is concerned, they are enemies for your sake; but as far as election is concerned, they are loved on account of the patriarchs, 29 for God’s gifts and his call are irrevocable. 30 Just as you who were at one time disobedient to God have now received mercy as a result of their disobedience, 31 so they too have now become disobedient in order that they too may now[a] receive mercy as a result of God’s mercy to you. 32 For God has bound everyone over to disobedience so that he may have mercy on them all.
