Again He convicts them by a parable, intimating both their unreasonable obstinacy, and the submissiveness of those who were utterly condemned by them. For these two children declare what came to pass with respect to both the Gentiles and the Jews. For the former not having undertaken to obey, neither having become hearers of the law, showed forth their obedience in their works; and the latter having said, “All that the Lord shall speak, we will do, and will hearken,”in their works were disobedient. And for this reason, let me add, that they might not think the law would benefit them, He shows that this self-same thing condemns them, like as Paul also saith, “Not the hearers of the law are just before God, but the doers of the law shall be justified.” For this intent, that He might make them even self-condemned, He causes the judgment to be delivered by themselves, like as He does also in the ensuing parable of the vineyard.
