I want you to imagine you are part of the mob that really hates the apostle Paul. Your mob preaches circumcision, blood sacrifices and eating clean foods. Paul preaches Christ crucified. Your mob preaches the Jews are God’s chosen children. Paul preaches that people from all nations are God’s children through faith in Jesus. Your mob preaches salvation by works. Paul preaches salvation by grace alone.
You and the mob really hate this guy! He preaches everything exactly the opposite from you.
