Romans 2:25–29

For circumcision indeed is of value if you obey the law, but if you break the law, your circumcision becomes uncircumcision. So, if a man who is uncircumcised keeps the precepts of the law, will not his uncircumcision be regarded as circumcision? Then he who is physically uncircumcised but keeps the law will condemn you who have the written code and circumcision but break the law. For no one is a Jew who is merely one outwardly, nor is circumcision outward and physical. But a Jew is one inwardly, and circumcision is a matter of the heart, by the Spirit, not by the letter. His praise is not from man but from God.

Circumcision has value if you observe the law, but if you break the law, you have become as though you had not been circumcised. So then, if those who are not circumcised keep the law’s requirements, will they not be regarded as though they were circumcised? The one who is not circumcised physically and yet obeys the law will condemn you who, even though you have the written code and circumcision, are a lawbreaker.

A person is not a Jew who is one only outwardly, nor is circumcision merely outward and physical. No, a person is a Jew who is one inwardly; and circumcision is circumcision of the heart, by the Spirit, not by the written code. Such a person’s praise is not from other people, but from God.

Circumcision benefits you if you observe the law, but if you are a lawbreaker, your circumcision has become uncircumcision. So if an uncircumcised man keeps the law’s requirements, will not his uncircumcision be counted as circumcision? A man who is physically uncircumcised, but who keeps the law, will judge you who are a lawbreaker in spite of having the letter of the law and circumcision. For a person is not a Jew who is one outwardly, and true circumcision is not something visible in the flesh. On the contrary, a person is a Jew who is one inwardly, and circumcision is of the heart—by the Spirit, not the letter. That person’s praise is not from people but from God.

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. And if the Gentiles obey God’s law, won’t God declare them to be his own people? 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.

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. 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.

For circumcision is of value if you do the law, but if you should be a transgressor of the law, your circumcision has become uncircumcision. Therefore, if the uncircumcised person follows the requirements of the law, will not his uncircumcision be credited for circumcision? And the uncircumcised person by nature who carries out the law will judge you who, though provided with the precise written code and circumcision are a transgressor of the law. For the Jew is not one outwardly, nor is circumcision outwardly, in the flesh. But the Jew is one inwardly, and circumcision is of the heart, by the Spirit, not by the letter, whose praise is not from people but from God.

For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision. Therefore if the uncircumcision keep the righteousness of the law, shall not his uncircumcision be counted for circumcision? And shall not uncircumcision which is by nature, if it fulfil the law, judge thee, who by the letter and circumcision dost transgress the law? For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.
