Philippians 3:1-7

Finally, my brethren, rejoice in the Lord. To write the same things again is no trouble to me, and it is a safeguard for you. Beware of the dogs, beware of the evil workers, beware of the false circumcision; for we are the true circumcision, who worship in the Spirit of God and glory in Christ Jesus and put no confidence in the flesh, although I myself might have confidence even in the flesh. If anyone else has a mind to put confidence in the flesh, I far more: circumcised the eighth day, of the nation of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; as to the Law, a Pharisee; as to zeal, a persecutor of the church; as to the righteousness which is in the Law, found blameless. But whatever things were gain to me, those things I have counted as loss for the sake of Christ.
