VERSE 21. Tell me, ye that desire to be under the law, do ye not hear the law? Here Paul would have closed his Epistle because he did not know what else to say. He wishes he could see the Galatians in person and straighten out their difficulties. But he is not sure whether the Galatians have fully understood the difference between the Gospel and the Law. To make sure, he introduces another illustration. He knows people like illustrations and stories. He knows that Christ Himself made ample use of parables. Paul is an expert at allegories. They are dangerous things. Unless a person has a thorough knowledge of Christian doctrine he had better leave allegories alone. The allegory which Paul is about to bring is taken from the Book of Genesis which he calls the Law. True, that book contains no mention of the Law. Paul simply follows the custom of the Jews who included the first book of Moses in the collective term, "Law." Jesus even included the Psalms.
