For we are the circumcision, which worship God in the spirit, and rejoice in Christ Jesus, and have no confidence in the flesh.
Circumcision indeed is of value if you obey the law; but if you break the law, your circumcision has become uncircumcision.
And he received the sign of circumcision, a seal of the righteousness which he had by faith while he was still uncircumcised, that he might be the father of all who believe but have not been circumcised, in order that righteousness might be reckoned to them.
In him you were also circumcised with a circumcision made without hands, by putting off the body of the flesh by the circumcision of Christ;
though I myself have reasons for confidence in the flesh. If anyone else thinks he has reasons to put confidence in the flesh, I have more:
1 Peter 1:23
For you have been born again, not of perishable seed, but of imperishable, through the living and enduring word of God.
And Mary said:
So, if a man who is uncircumcised keeps the requirements of the law, will not his uncircumcision be regarded as circumcision?
since there is one God, who will justify the circumcised by faith and the uncircumcised through their faith.
1 Corinthians 1:31
therefore, as it is written, "Let him who boasts, boast in the Lord."
2 Corinthians 10:17
But, "Let him who boasts boast in the Lord."
so that your proud confidence in me may abound in Christ Jesus through my coming to you again.
