Romans 9:30. The Gentiles, who didn’t follow after righteousness, attained to righteousness, even the righteousness, which is of faith.
Romans 10:9-11. If you will confess with your mouth that Jesus is Lord, and believe in your heart that God raised him from the dead, you will be saved. For with the heart, one believes unto righteousness; and with the mouth confession is made unto salvation. For the Scripture says, “Whoever believes in him will not be disappointed.”
Romans 10:13-15. “Whoever will call on the name of the Lord will be saved.” How then will they call on him in whom they have not believed? How will they believe in him whom they have not heard? How will they hear without a preacher? And how will they preach unless they are sent? As it is written: “How beautiful are the feet of those who preach the Good News of peace, who bring glad tidings of good things!”
Romans 10:16. They didn’t all listen to the glad news. For Isaiah says, “Lord, who has believed our report?”
Romans 11:16-21. If the first fruit is holy, so is the lump. If the root is holy, so are the branches. But if some of the branches were broken off, and you, being a wild olive, were grafted in among them, and became partaker with them of the root and of the richness of the olive tree; don’t boast over the branches. But if you boast, it is not you who support the root, but the root supports you. You will say then, “Branches were broken off, that I might be grafted in.” True; by their unbelief they were broken off, and you stand by your faith. Don’t be conceited, but fear; for if God didn’t spare the natural branches, neither will he spare you.
Romans 11:33. Oh the depth of the riches both of the wisdom and the knowledge of God! How unsearchable are his judgments, and his ways past tracing out!
