Philippians 3:2-7

2Look out for the dogs, look out for the evildoers, look out for those who mutilate the flesh.

3For we are the circumcision, who worship by the Spirit of God and glory in Christ Jesus and put no confidence in the flesh—

4though I myself have reason for confidence in the flesh also. If anyone else thinks he has reason for confidence in the flesh, I have more:

5circumcised on the eighth day, of the people of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; as to the law, a Pharisee;

6as to zeal, a persecutor of the church; as to righteousness under the law, blameless.

7But whatever gain I had, I counted as loss for the sake of Christ.
