How did Paul approach Jews and Gentiles when he preached?
Paul carried the revealed doctrines of grace primarily to the Gentiles, yet he went to the Jew first. He would begin in the Jewish synagogue, and when the Jews rejected the message, he took it down the street to the Gentiles. His apostolic mission focused on Gentiles while still giving Jews the first opportunity.
Les explains that in the Old Testament everything was for Israel’s benefit, but Paul’s apostleship is for Gentiles. Paul received the dispensation or administration of the grace of God, and God revealed to him the doctrines of grace. Unlike Moses, who went to Israel and Israel alone, Paul took this message primarily to the Gentiles. Even so, Les points out that Paul went to the Jew first: he would always go to the synagogue of the Jew for his opening, and when they rejected it, he went down the street to the Gentiles. Paul then refers to this in Galatians chapter 1 and verse 10, where he says if he pleased men he could not be that bond slave of Christ.
