Dr. Alex McFarland "disagreed" with the Apostle Paul on the 7/16/2018 Janet Mefferd Show that he is the chief of sinners, not Paul.
On might think this is an act of humility. But I think it is just the opposite. Pride is making one "better" than other. He is proud for being witty, so he would think.
So, I would ask...how are you the chief of sinners? And what are you doing about it? Now compare your answers to Paul.
Luke 7:47 comes to mind.
