John Wesley on Acts 13:46

Then Paul and Barnabas speaking boldly, said - Those who hinder others must be publicly reproved. It was necessary - Though ye are not worthy: he shows that he had not preached to them, from any confidence of their believing, but seeing ye judge yourselves unworthy of eternal life - They indeed judged none but themselves worthy of it. Yet their rejecting of the Gospel was the same as saying, "We are unworthy of eternal life." Behold! - A thing now present! An astonishing revolution! We turn to the Gentiles - Not that they left off preaching to the Jews in other places. But they now determined to lose no more time at Antioch on their ungrateful countrymen, but to employ themselves wholly in doing what they could for the conversion of the Gentiles there.
