Philippians 3:3-7

for we [who are born-again have been reborn from above—spiritually transformed, renewed, set apart for His purpose and] are the true circumcision, who worship in the Spirit of God and glory and take pride and exult in Christ Jesus and place no confidence [in what we have or who we are] in the flesh— though I myself might have [some grounds for] confidence in the flesh [if I were pursuing salvation by works]. If anyone else thinks that he has reason to be confident in the flesh [that is, in his own efforts to achieve salvation], I have far more: circumcised when I was eight days old, of the nation of Israel, of the tribe of Benjamin, a Hebrew of Hebrews [an exemplary Hebrew]; as to the [observance of the] Law, a Pharisee; as to my zeal [for Jewish tradition], a persecutor of the church; and as to righteousness [supposed right living] which [my fellow Jews believe] is in the Law, I proved myself blameless. But whatever former things were gains to me [as I thought then], these things [once regarded as advancements in merit] I have come to consider as loss [absolutely worthless] for the sake of Christ [and the purpose which He has given my life].
