What had Paul heard about the Galatian believers?
Paul had heard that the Galatian believers were being besieged by Judaizers who wanted to bring them back under the Law, practice circumcision, and temple worship. He had heard they were being hoodwinked to return to legalism, moving from the grace of Christ to another gospel.
Les explains that Paul had gotten word the Galatian believers were being besieged by Judaizers who wanted to bring them back under the Law, practice circumcision, and temple worship. Paul was getting to the heart of the matter and marveled, unable to comprehend how these people, who as the Thessalonians had turned from idols to the living God, were now not satisfied. They were being hoodwinked to go back under legalism. Paul said he could not comprehend that they were so soon removed from Him who called them into the grace of Christ, or the Gospel of the Grace of Christ, into another gospel.
