Romans 10:12-13 : For there is no distinction between Jew and Greek: for the same Lord is Lord of all, and rich unto all that call upon him: for, Whosoever shall call upon the name of the Lord shall be saved. Under the law there was a distinction between Jew and Gentile, but this was not a matter of favoritism. God was working out his greater plan, the plan in which Jew and Gentile would have the same standing before Jehovah. But the law of Moses--all things Jewish--had to be taken out of the way before both Jew and Gentile could be brought together into one body, one worshiping assembly (Ephesians 2:13-18). In Paul's writings are many arguments to show that the law of Moses ended at the cross, but some of the professed Christians among the Jews never did recognize that the Jew had no advantage over the Gentile. His claim that God now made no distinction between Jew and Gentile, and his preaching to the Gentiles, made these Jews very bitter toward him.
They would not recognize that the riches of God's grace were as abundant for the Gentiles, as for the Jew. It is: "Whosoever will." In this the gospel of Christ is much more glorious than the law, as it is also in many other respects.
