The carnal mind is at enmity against God (Rom. 8:7), and the more His children are conformed to His image the more they will bring down upon themselves the spite of His foes. Being “persecuted for righteousness sake” (Mt. 5:10) means being opposed because of right living. Those who perform their Christian duty condemn those who live to please self, and therefore evoke their hatred. This persecution assumes various forms, from annoying and taunting to opposing and tormenting.
