Galatians 4:10

To regard the observance of certain days as in itself meritorious as a work, is alien to the free spirit of Christianity. This is not incompatible with observing the Sabbath or the Christian Lord's day as obligatory, though not as a work (which was the Jewish and Gentile error in the observance of days), but as a holy mean appointed by the Lord for attaining the great end, holiness. The whole life alike belongs to the Lord in the Gospel view, just as the whole world, and not the Jews only, belong to Him. But as in Paradise, so now one portion of time is needed wherein to draw off the soul more entirely from secular business to God (Col 2:16). "Sabbaths, new moons, and set feasts" (Ch1 23:31; Ch2 31:3), answer to "days, months, times." "Months," however, may refer to the first and seventh months, which were sacred on account of the number of feasts in them. times--Greek, "seasons," namely, those of the three great feasts, the Passover, Pentecost, and Tabernacles. years--The sabbatical year was about the time of writing this Epistle, A.D. 48 [BENGEL].

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.

4:10-11 Circumcision was not the Galatians’ only attempt to follow the law; it was one example of a whole way of thinking. They had also begun celebrating the Jewish festivals, thinking that it would make them more acceptable to God. To Paul, it was another indication that they did not understand, or had turned their backs on, the Good News of God’s grace through Christ.
