Rom 11:14

“By his attentive care and close attention to the teaching of the Gentiles and by making their behavior worthy of eternal life, Paul is inviting and provoking the Jews who see these things and who are his kinsmen according to the flesh to imitate those who are progressing in the faith of God. It is the glory of his ministry that he can use the teaching of the Gentiles to reach some of his own people as well.”

“Paul will always present himself to the Jews in such a way that they will want to imitate him.”

“Paul evangelized the Gentiles of necessity, addressing himself to them and showing that the prophets had predicted this many centuries before. His aim was to make the Jews jealous and thus encourage some of them to come to salvation also.”

“Hence he adds: if, by any means, I may provoke to emulation them who are my flesh, i.e., the Jews, who are my kinsmen according to the flesh (Rom 9:3): do not despise your own flesh (Isa 58:7). And that they may emulate by good emulation, as is said in 1 Corinthians: emulate the better gifts (1 Cor 12:31). And in this way I may save some of them, namely, of the Jews: not seeking my own advantage but that of many, that they may be saved (1 Cor 10:33). But this seems contrary to what he says in 2 Corinthians: but we will not boast beyond limit, but will keep to the limits God apportioned us, to reach even to you (2 Cor 10:13). But he had not accepted the limit of his service, which was to the gentiles. Therefore, he should not have concerned himself about the Jews. Some say that the Jews living in Judea did not pertain to his apostolate, but to that of Peter, James, and John (Gal 2:7). But the Jews living among the gentiles pertained to his apostolate and he worked for their salvation. But this seems contrary to his statement here. For if those Jews were the limit of his apostolate, he would not be magnifying his service. Therefore, it must be said that preaching to the gentiles was committed to him in such a way that he was bound to it by necessity, as he says: woe to me if I do not preach the Gospel. For necessity is laid upon me (1 Cor 9:16); but he was not forbidden to preach to the Jews, even though he was not bound to do so. Consequently, by working for their salvation he magnified his service. But he would not have done this, if he thought their fall irreparable. Hence the Apostle's very zeal for the conversion of the Jews was the sign he adduced for stating that the fall of the Jews was reparable.”
