You Gentiles: Paul speaks directly to the gentile believers in Rome. His purpose is to correct them for thinking too highly of themselves, especially when comparing themselves to their Jewish brothers and sisters (11:20). Paul reminds them that they enjoy salvation only because of God’s kindness, not because of their own merit (11:22). He also explains that God’s goal is not to reject the Jews. Instead, God intends to lead them to repentance and renewed faith (11:23).
I magnify my ministry: Paul explains why he focused his work on the Gentiles. He believed that when Gentiles came to faith, this would help lead Jews to salvation as well. In this way, Paul saw his ministry to the Gentiles as part of God’s larger plan to save both groups.
