VERSE 13. For neither they themselves who are circumcised keep the law; but desire to have you circumcised, that they may glory in your flesh. In other words: "I shall tell you what kind of teachers you have now. They avoid the Cross, they teach no certain truths. They think they are performing the Law, but they are not. They have not the Holy Spirit and without Him nobody can keep the Law." Where the Holy Ghost does not dwell in men there dwells an unclean spirit, a spirit that despises God and turns every effort at keeping the Law into a double sin. Mark what the Apostle is saying: Those who are circumcised do not fulfill the Law. No self-righteous person ever does. To work, pray, or suffer apart from Christ is to work, pray, and to suffer in vain, "for whatsoever is not of faith is sin." It does a person no good to be circumcised, to fast, to pray, or to do anything, if in his heart he despises Christ. "Why do the false apostles insist that you should be circumcised? Not for the sake of your righteousness," although they give that impression, but "that they may glory in your flesh." Now what sort of an ambition is that? Worst of all, they force circumcision upon you for no other reason than the satisfaction they get out of your submission.
