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:
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;
as to zeal, a persecutor of the church; as to righteousness under the law, blameless.
Yet whatever gains I had, these I have come to regard as loss because of Christ.
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
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, the righteousness from God based on faith.
