What was the content of Paul's gospel to the Gentiles?
Paul's gospel to the Gentiles was the message that God would bring Gentile, pagan, idolatrous people into reconciliation with Himself outside of Judaism and apart from the law. It was an advance beyond what Jerusalem Jews knew, revealed supernaturally, and stood against the Judaizers' legalism.
Les explains that Paul wrote to the churches in Asia Minor who were being deluged with Judaizers trying to bring Gentile believers under the law and legalism. Paul went up to Jerusalem by revelation, a supernatural trip, and communicated the gospel he preached among the Gentiles. Les teaches that this gospel was totally different from what the Jews in Jerusalem knew; it was an advance, yet they could not comprehend that God would now go to the Gentile, pagan, idolatrous world and bring those people into reconciliation with Himself outside of Judaism. This was the content of Paul's gospel to the Gentiles.
And I went up by revelation, and communicated unto them that gospel which I preach among the Gentiles, but privately to them which were of reputation, lest by any means I should run, or had run, in vain.
