Philippians 3:1-6

Finally, my fellow believers, continue to rejoice and delight in the LORD. To write the same things again is no trouble for me, and it is a safeguard for you. Look out for the dogs [the Judaizers, the legalists], look out for the troublemakers, look out for the false circumcision [those who claim circumcision is necessary for salvation]; 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.
