25 The Jewish ceremony of circumcision has value only if you obey God's law. But if you don't obey God's law, you are no better off than an uncircumcised Gentile. 26 And if the Gentiles obey God's law, won't God declare them to be his own people? 27 In fact, uncircumcised Gentiles who keep God's law will condemn you Jews who are circumcised and possess God's law but don't obey it. 28 For you are not a true Jew just because you were born of Jewish parents or because you have gone through the ceremony of circumcision. 29 No, a true Jew is one whose heart is right with God. And true circumcision is not merely obeying the letter of the law; rather, it is a change of heart produced by the Spirit. And a person with a changed heart seeks praise from God, not from people.

Commentary on Romans 2:25-29
(Read Romans 2:25-29)
No forms, ordinances, or notions can profit, without regenerating grace, which will always lead to seeking an interest in the righteousness of God by faith. For he is no more a Christian now, than he was really a Jew of old, who is only one outwardly: neither is that baptism, which is outward in the flesh: but he is the real Christian, who is inwardly a true believer, with an obedient faith. And the true baptism is that of the heart, by the washing of regeneration and the renewal of the Holy Ghost; bringing a spiritual frame of mind, and a willing following of truth in its holy ways. Let us pray that we may be made real Christians, not outwardly, but inwardly; in the heart and spirit, not in the letter; baptized, not with water only, but with the Holy Ghost; and let our praise be, not of men, but of God.
