Exasperated, Paul wonders at the Galatians’ desire to place themselves back under the yoke of the Law. He worries over them as they fall victim to Judaizers who wish them circumcised, observant of certain days and specific customs. Paul says “it is always good to be enthusiastic about good;” but he also says he is “suffering labor pains for you until Christ is formed in you.” Paul strongly suggests to the church at Galatia that observing the Law does not and can not make them any more Christ-like!
15 What happened to this sense of being blessed you had? For I testify to you that, if possible, you would have torn out your eyes and given them to me. 16 Have I now become your enemy by telling you the truth? 17 They are enthusiastic about you, but not for any good. Instead, they want to isolate you so you will be enthusiastic about them. 18 Now it is always good to be enthusiastic about good—and not just when I am with you. 19 My children, I am again suffering labor pains for you until Christ is formed in you. 20 I would like to be with you right now and change my tone of voice, because I don’t know what to do about you. 21 Tell me, those of you who want to be under the law, don’t you hear the law?
Paul then tells them a story. He reminds the Galatians of the children of the free woman, Sarah and the slave woman, Hagar. Both children come from Abraham, but only one is the true heir.
Rid yourself of the yoke of slavery and take up the cloak of freedom in Christ.
