25 Circumcision indeed is of value if you obey the law; but if you break the law, your circumcision has become uncircumcision. 26 So, if those who are uncircumcised keep the requirements of the law, will not their uncircumcision be regarded as circumcision? 27 Then those who are physically uncircumcised but keep the law will condemn you that have the written code and circumcision but break the law. 28 For a person is not a Jew who is one outwardly, nor is true circumcision something external and physical. 29 Rather, a person is a Jew who is one inwardly, and real circumcision is a matter of the heart—it is spiritual and not literal. Such a person receives praise not from others but from God.
Trapper has already decided the answer to that one. It only remains for you to draw your own conclusions from the example passage above. There are many more to similar effect, but seriously, you should do your own research 'to see if these things are so'.
