Sermon Text: Galatians 4:21-31
Theme: The parentage of Isaac and Ishmael teaches the Church a spiritual lesson: only those who trust in God’s grace for salvation, apart from reliance on human effort, will inherit eternal blessing.
Structure/points: The Judaizing heretics had nearly convinced the Galatians that the law of Moses requires them to keep it in order to be saved. But Paul saw that though the Judaizers and Galatians desired to be slaves to the law, they didn’t actually listen to the law, and they did not understand. Since Paul is trying to restore the faith of the Galatians, he reminds them of Abraham’s family and explains that the law itself teaches that salvation is only by the grace of God.
