Note 11 at Php 3:6: Paul's list of human attainments is impressive. He was a circumcised, full-blooded Jew of an outstanding tribe of Israel. As a Pharisee, he once guarded the Law with zeal. As for legalistic righteousness, he had been blameless. But in comparison to God's own righteousness, he had failed. The truth is that we all have sinned and come short of the glory of God (Ro 3:23). It doesn't matter how good we are, we still need a Savior. Who wants to be the best sinner who ever went to hell?
