4 Bible Verses about True Circumcision

In whom also ye are circumcised with the circumcision not performed by hands, in putting off the body of the sins of the flesh, by the circumcision which is of Christ:

nor is that circumcision, which is only in appearance, in the flesh;

For we are of the true circumcision, who worship God in spirit, rejoicing in Christ Jesus, and having no confidence in the flesh.

Therefore if the uncircumcised keep the righteous precepts of the law, shall not his uncircumcision be accounted to him for circumcision?
