Why was the letter to the Galatians written?
The letter to the Galatians was written specifically to the churches of Galatia to prove to Gentile believers that they were not under law but under grace. Judaizers were trying to put them under the law, so the letter countered that by showing believers are under grace, not law.
Les explains that the letter to the Galatians was written specifically to the churches of Galatia because the Judaizers were trying to put them under law. Its purpose was to prove to these Gentile believers that they were not under law but under grace. The letter uses the analogy of Isaac and Ishmael: Ishmael was of the flesh and stood for the law and legalism, while Isaac stood for grace and freedom. Scripture says to cast out the bondwoman and her son, for the son of the bondwoman shall not be heir with the son of the free woman. Law and grace cannot be mixed.
