Paul doesn’t pull any punches here. Philippians is the epistle of joy, but Paul takes a very different tone, a very different tactic right here. When you love someone, there is a protective instinct that you feel towards them. If you mess with my wife or with my kids, I will take you down! Why? I care more about them than I do myself. Paul’s protective instincts take over right here. He loves the Philippians too much to sit idly by and watch false prophets with false motives teach false doctrine.
