Galater 4:29

persecuted--Ishmael "mocked" Isaac, which contained in it the germ and spirit of persecution (Gen 21:9). His mocking was probably directed against Isaac's piety and faith in God's promises. Being the older by natural birth, he haughtily prided himself above him that was born by promise: as Cain hated Abel's piety. him . . . born after the Spirit--The language, though referring primarily to Isaac, born in a spiritual way (namely, by the promise or word of God, rendered by His Spirit efficient out of the course of nature, in making Sarah fruitful in old age), is so framed as especially to refer to believers justified by Gospel grace through faith, as opposed to carnal men, Judaizers, and legalists. even so it is now-- (Gal 5:11; Gal 6:12, Gal 6:17; Act 9:29; Act 13:45, Act 13:49-50; Act 14:1-2, Act 14:19; Act 17:5, Act 17:13; Act 18:5-6). The Jews persecuted Paul, not for preaching Christianity in opposition to heathenism, but for preaching it as distinct from Judaism. Except in the two cases of Philippi and Ephesus (where the persons beginning the assault were pecuniarily interested in his expulsion), he was nowhere set upon by the Gentiles, unless they were first stirred up by the Jews. The coincidence between Paul's Epistles and Luke's history (the Acts) in this respect, is plainly undesigned, and so a proof of genuineness (see PALEY, HorÃ&brvbr PaulinÃ&brvbr).

The apostle, in this chapter, is still carrying on the same general design as in the former - to recover these Christians from the impressions made upon them by the judaizing teachers, and to represent their weakness and folly in suffering themselves to be drawn away from the gospel doctrine of justification, and to be deprived of their freedom from the bondage of the law of Moses. For this purpose he makes use of various considerations; such as, I. The great excellence of the gospel state above the legal (Gal 4:1-7). II. The happy change that was made in them at their conversion (Gal 4:8-11). III. The affection they had had for him and his ministry (Gal 4:12-16). IV. The character of the false teachers by whom they had been perverted (Gal 4:17, Gal 4:18). V. The very tender affection he had for them (Gal 4:19, Gal 4:20). VI. The history of Isaac and Ishmael, by a comparison taken from which he illustrates the difference between such as rested in Christ and such as trusted in the law. And in all these, as he uses great plainness and faithfulness with them, so he expresses the tenderest concern for them.

4:29 Ishmael persecuted Isaac, the child of the promise, at Isaac’s weaning ceremony (see Gen 21:9). Similarly, in Galatia, those who want you to keep the law were persecuting those who trusted in God’s promise, the message of God’s grace through faith in Christ alone (cp. Acts 13:50-51; 14:1-7).
