Romans 10 - Israel - Israel has not obtained the righteousness of God, for they tried to establish their own by the law. But no one is justified by the law. God has shown us how to be justified. 
vs.9,10 “If you confess with your mouth Jesus as Lord, and believe in your heart that God raised him from the dead, you shall be saved; for with the heart man believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation.”
There is no difference between Jew and Greek, everyone must come to God by faith in Jesus. God made himself known, in his son Jesus, to the Jews. He gave them the Law and the Prophets. But this is the testimony God gave about Israel, “All the day long I have stretched out my hands to a disobedient and obstinate people.”
