Romans 2:23-29

23You who boast in the law, do you dishonor God by breaking the law?

24As it is written: “God’s name is blasphemed among the Gentiles because of you.”

25Circumcision has value if you observe the law, but if you break the law, you have become as though you had not been circumcised.

26So then, if those who are not circumcised keep the law’s requirements, will they not be regarded as though they were circumcised?

27The 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.

28A person is not a Jew who is one only outwardly, nor is circumcision merely outward and physical.

29No, 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.
