26. Cursed is he that confirmeth not. Although it was God’s purpose to summon the consciences of all men before Him, and, in order that they might not only fear human judgments, He designedly threatened them with the punishment of secret sins, yet the conclusion, which is now added, extends the same judgment to all iniquities of whatever kind. Nay, He briefly declares, that whosoever shall not perform what the Law requires, are accursed. From whence Paul rightly infers, that “as many as are of the works of the Law are under the curse.” (Galatians 3:10.) For let the most perfect man come forward, and, although he may have striven ever so diligently to keep the Law, he will have at least offended in some point or other; since the declaration of James must be borne in mind, “Whosoever shall keep the whole law, and yet offend in one point, he is guilty of all;” for he that forbade murder and adultery, forbade theft also. (James 2:10.) Paul indeed does not quote the very words of Moses, for he thus cites his testimony;
“Cursed is every one that continueth not in all things which are written in the book of the law to do them,” (Galatians 3:10;)
but there is no difference in the sense, since all are here condemned without exception, who have not confirmed the Law of God, so as to fulfill to the uttermost whatever it contains. Whence if is clear that, in whatever respect the deficiency betrays itself, it brings men under the curse; and to this the Israelites are commanded to assent, so as to acknowledge that they were all without exception lost, since they were involved in the curse. And now-a-days, also, it is necessary that we should all to a man be struck with the same despair, in order that, embracing the grace of Christ, we should be delivered from this melancholy state of guilt; since he was made accursed for us, that He might redeem us from the curse of the Law. (Galatians 3:13.)
