4:8-11 The happy change whereby the Galatians were turned from idols to the living God, and through Christ had received the adoption of sons, was the effect of his free and rich grace; they were laid under the greater obligation to keep to the liberty wherewith he had made them free. All our knowledge of God begins on his part; we know him because we are known of him. Though our religion forbids idolatry, yet many practise spiritual idolatry in their hearts. For what a man loves most, and cares most for, that is his god: some have their riches for their god, some their pleasures, and some their lusts. And many ignorantly worship a god of their own making; a god made all of mercy and no justice. For they persuade themselves that there is mercy for them with God, though they repent not, but go on in their sins. It is possible for those who have made great professions of religion, to be afterwards drawn aside from purity and simplicity. And the more mercy God has shown, in bringing any to know the gospel, and the liberties and privileges of it, the greater their sin and folly in suffering themselves to be deprived of them. Hence all who are members of the outward church should learn to fear and to suspect themselves. We must not be content because we have some good things in ourselves. Paul fears lest his labour is in vain, yet he still labours; and thus to do, whatever follows, is true wisdom and the fear of God. This every man must remember in his place and calling.
9. known God or rather are known of God—They did not first know and love God, but God first, in His electing love, knew and loved them as His, and therefore attracted them to the saving knowledge of Him (Mt 7:23; 1Co 8:3; 2Ti 2:19; compare Ex 33:12, 17; Joh 15:16; Php 3:12). God's great grace in this made their fall from it the more heinous.
how—expressing indignant wonder at such a thing being possible, and even actually occurring (Ga 1:6). "How is it that ye turn back again?"
weak—powerless to justify: in contrast to the justifying power of faith (Ga 3:24; compare Heb 7:18).
beggarly—contrasted with the riches of the inheritance of believers in Christ (Eph 1:18). The state of the "child" (Ga 4:1) is weak, as not having attained manhood; "beggarly," as not having attained the inheritance.
elements—"rudiments." It is as if a schoolmaster should go back to learning the A, B, C'S [Bengel].
again—There are two Greek words in the original. "Ye desire again, beginning afresh, to be in bondage." Though the Galatians, as Gentiles, had never been under the Mosaic yoke, yet they had been under "the elements of the world" (Ga 4:3): the common designation for the Jewish and Gentile systems alike, in contrast to the Gospel (however superior the Jewish was to the Gentile). Both systems consisted in outward worship and cleaved to sensible forms. Both were in bondage to the elements of sense, as though these could give the justification and sanctification which the inner and spiritual power of God alone could bestow.
ye desire—or "will." Will-worship is not acceptable to God (Col 2:18, 23).
