'Circumcision' in the Bible

For circumcision benefits you if you observe the law, but if you are a lawbreaker, your circumcision has become uncircumcision.

Therefore if an uncircumcised man keeps the law’s requirements, will his uncircumcision not be counted as circumcision?

A man who is physically uncircumcised, but who fulfills 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 man’s praise is not from men but from God.

So what advantage does the Jew have? Or what is the benefit of circumcision?

And he received the sign of circumcision as a seal of the righteousness that he had by faith while still uncircumcised. This was to make him the father of all who believe but are not circumcised, so that righteousness may be credited to them also.
