Galations 4:4, 5, “God sent forth his Son, made of a woman, made under the law, to redeem them that were under the law.” He was both made of a woman, and made under the law; that is, obedient to it for us. The end here, both of the incarnation and obedience of Christ to the law was all to redeem us. In these two expressions, “Made of a woman, made under the law,” the apostle does not knit his incarnation and death together, with an exclusion of the obedience of his life. And he was so made under the law, as those were under the law whom he was to redeem. Now, we were under the law, not only as obnoxious to its penalties, but as bound to all the duties of it. That this is our being “under the law,” the apostle informs us, Gal. 4:21, “Tell me, ye that desire to be under the law.” It was not the penalty of the law they desired to be under, but to be under it in respect of obedience. Take away, then, the end, and you destroy the means. If Christ were not incarnate nor made under the law for himself, he did not yield obedience for himself; it was all for us, for our good.
