But now, after that ye have known God,
&c,] God in Christ, as their covenant God and Father, through the preaching of the Gospel, and in the light of divine grace; God having caused light to shine in their dark hearts; and having given them the light of the knowledge of himself in the face of Christ, and having sent down into their hearts the Spirit of his Son, crying "Abba", Father.
Or rather are known of God;
for it is but little that the best of these, that have the greatest share of knowledge, know of him; and what knowledge they have, they have it first, originally, and wholly from him: that knowledge which he has of them is particular, distinct, and complete; and is to be understood, not of his omniscience in general, so all men are known by him; but of his special knowledge, joined with affection, approbation, and care: and the meaning is, that they were loved by him with an everlasting love, which had been manifested in their conversion, in the drawing of them to himself, and to his Son; that he approved of them, delighted in them, had an exact knowledge, and took special care of them: but, oh, folly and ingratitude!
how turn ye again to the weak and beggarly elements,
desire again to be in bondage?
meaning the ordinances of the ceremonial law, he before calls "the elements of the world", and here "weak", because they could not give life, righteousness, peace, joy, comfort, and salvation; and, since the coming of Christ, were become impotent to all the uses they before served; and beggarly, because they lay in the observation of mean things, as meats, drinks and which were only shadows of those good things, the riches of grace and glory, which come by Christ. The Galatians are said to turn again to these; not that they were before in the observation of them, except the Jews, but because there was some likeness between these, and the ceremonies with which they carried on the service of their idols; and by showing an inclination to them, they discovered a good will to come into a like state of bondage they were in before; than which nothing could be more stupid and ungrateful in a people that had been blessed with so much grace, and with such clear Gospel light and knowledge.
