Philippians 3:3-5

3But we are truly God's people. And it is not because someone has circumcised us. It is God's own Spirit that leads us to worship God. We thank God because of what Christ Jesus has done for us. We know that it is not human ideas that can save us.

4For myself, I could have trusted those human ideas. Perhaps somebody may think that they could trust in those things to save them. Then I would have an even better reason to trust in them.

5I belong to Israel's people, to Benjamin's tribe. I am a true Jew. They circumcised me when I was eight days old. I was a Pharisee, and I obeyed the Jewish rules very carefully.
