Philippians 3:4-9

although I have reasons for confidence in the flesh. If anyone else thinks he has grounds for confidence in the flesh, I have more: circumcised the eighth day; of the nation of Israel, of the tribe of Benjamin, a Hebrew born of Hebrews; regarding the law, a Pharisee; regarding zeal, persecuting the church; regarding the righteousness that is in the law, blameless. But everything that was a gain to me, I have considered to be a loss because of Christ. More than that, I also consider everything to be a loss in view of the surpassing value of knowing Christ Jesus my Lord. Because of him I have suffered the loss of all things and consider them as dung, so that I may gain Christ and be found in him, not having a righteousness of my own from the law, but one that is through faith in Christ  — the righteousness from God based on faith.
