Philippians 3:4-11 New Revised Standard Version (NRSV)
4 even though I, too, have reason for confidence in the flesh.
If anyone else has reason to be confident in the flesh, I have more: 5 circumcised on the eighth day, a member of the people of Israel, of the tribe of Benjamin, a Hebrew born of Hebrews; as to the law, a Pharisee; 6 as to zeal, a persecutor of the church; as to righteousness under the law, blameless.
7 Yet whatever gains I had, these I have come to regard as loss because of Christ. 8 More than that, I regard everything as loss because of the surpassing value of knowing Christ Jesus my Lord. For his sake I have suffered the loss of all things, and I regard them as rubbish, in order that I may gain Christ 9 and be found in him, not having a righteousness of my own that comes from the law, but one that comes through faith in Christ,[a] the righteousness from God based on faith. 10 I want to know Christ[b] and the power of his resurrection and the sharing of his sufferings by becoming like him in his death, 11 if somehow I may attain the resurrection from the dead.
