If someone else thinks they have reasons to put confidence in the flesh, I have more:  circumcised on the eighth day, of the people of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; in regard to the law, a Pharisee; as for zeal, persecuting the church; as for righteousness based on the law, faultless. But whatever were gains to me I now consider loss for the sake of Christ.  What is more, I consider everything a loss because of the surpassing worth of knowing Christ Jesus my Lord, for whose sake I have lost all things. I consider them garbage, that I may gain Christ.

Philippians 3:4b-8
