1 Corinthians 7:19
For neither circumcision counts for anything nor uncircumcision, but keeping the commandments of God.
Circumcise yourselves to the Lord; remove the foreskin of your hearts, O men of Judah and inhabitants of Jerusalem; lest my wrath go forth like fire, and burn with none to quench it, because of the evil of your deeds.

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.
For neither circumcision counts for anything, nor uncircumcision, but a new creation.
This is my covenant, which you shall keep, between me and you and your offspring after you: Every male among you shall be circumcised. You shall be circumcised in the flesh of your foreskins, and it shall be a sign of the covenant between me and you. He who is eight days old among you shall be circumcised. Every male throughout your generations, whether born in your house or bought with your money from any foreigner who is not of your offspring, both he who is born in your house and he who is bought with your money, shall surely be circumcised. So shall my covenant be in your flesh an everlasting covenant. Any uncircumcised male who is not circumcised in the flesh of his foreskin shall be cut off from his people; he has broken my covenant.
He received the sign of circumcision as a seal of the righteousness that he had by faith while he was still uncircumcised. The purpose was to make him the father of all who believe without being circumcised, so that righteousness would be counted to them as well,
But even Titus, who was with me, was not forced to be circumcised, though he was a Greek.
For in Christ Jesus neither circumcision nor uncircumcision counts for anything, but only faith working through love.
And at the end of eight days, when he was circumcised, he was called Jesus, the name given by the angel before he was conceived in the womb.
For we are the circumcision, who worship by the Spirit of God and glory in Christ Jesus and put no confidence in the flesh—
Circumcise therefore the foreskin of your heart, and be no longer stubborn.
For no one is a Jew who is merely one outwardly, nor is circumcision outward and physical.
And on the eighth day the flesh of his foreskin shall be circumcised.
1 Corinthians 7:18
Was anyone at the time of his call already circumcised? Let him not seek to remove the marks of circumcision. Was anyone at the time of his call uncircumcised? Let him not seek circumcision.
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.

Therefore remember that at one time you Gentiles in the flesh, called “the uncircumcision” by what is called the circumcision, which is made in the flesh by hands—
