Appeal to them not to turn back from their privileges as free sons, to legal bondage again. then--when ye were "servants" (Gal 4:7). ye knew not God--not opposed to Rom 1:21. The heathen originally knew God, as Rom 1:21 states, but did not choose to retain God in their knowledge, and so corrupted the original truth. They might still have known Him, in a measure, from His works, but as a matter of fact they knew Him not, so far as His eternity, His power as the Creator, and His holiness, are concerned. are no gods--that is, have no existence, such as their worshippers attribute to them, in the nature of things, but only in the corrupt imaginations of their worshippers (see on Co1 8:4; Co1 10:19-20; Ch2 13:9). Your "service" was a different bondage from that of the Jews, which was a true service. Yet theirs, like yours, was a burdensome yoke; how then is it ye wish to resume the yoke after that God has transferred both Jews and Gentiles to a free service?

In these verses the apostle puts them in mind of what they were before their conversion to the faith of Christ, and what a blessed change their conversion had made upon them; and thence endeavours to convince them of their great weakness in hearkening to those who would bring them under the bondage of the law of Moses. I. He reminds them of their past state and behaviour, and what they were before the gospel was preached to them. Then they knew not God; they were grossly ignorant of the true God, and the way wherein he is to be worshipped: and at that time they were under the worst of slaveries, for they did service to those which by nature were no gods, they were employed in a great number of superstitious and idolatrous services to those who, though they were accounted gods, were yet really no gods, but mere creatures, and perhaps of their own making, and therefore were utterly unable to hear and help them. Note, 1. Those who are ignorant of the true God cannot but be inclined to false gods. Those who forsook the God who made the world, rather than be without gods, worshipped such as they themselves made. 2. Religious worship is due to none but to him who is by nature God; for, when the apostle blames the doing service to such as by nature were no gods, he plainly shows that he only who is by nature God is the proper object of our religious worship. II. He calls upon them to consider the happy change that was made in them by the preaching of the gospel among them. Now they had known God (they were brought to the knowledge of the true God and of his Son Jesus Christ, whereby they were recovered out of the ignorance and bondage under which they before lay) or rather were known of God; this happy change in their state, whereby they were turned from idols to the living Go…

4:8-11 Paul reminds the Galatians of their former paganism; he argues that practicing circumcision (and the law in general) would be a return to the same kind of slavery that they experienced before they knew God. 4:8 The Gentile Galatians had previously practiced pagan idolatry; they worshiped the elements and the seasons (cp. Rom 1:25) and were slaves to the fear of offending these so-called gods (1 Cor 8:5-6).
