Expositor's Bible Commentary Commentary Acts 13:43

"Now when the synagogue broke up, many of the Jews and of the devout proselytes followed Paul and Barnabas; who, speaking to them, urged them to continue in the grace of God." — Acts 13:43 (ASV)

Those who heard Paul’s sermon requested Paul and Barnabas “to speak further about these things on the next Sabbath.” More than likely the synagogue authorities took a less favorable view of the sermon. But “many of the Jews and devout converts to Judaism” were interested and after the service followed the apostles to hear more. And “some” of those who did this were “persuaded” (NIV “urged”) by the apostles “to continue in the grace of God”—which, to judge by Paul’s usual understanding of grace, must connote continuance in the Good News about salvation through Jesus.
