Philippians 3:4-7

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.
