Context

“Thinking he knows enough, a person begins little by little to despise the Word until he has lost Christ and the Gospel altogether. Let every believer carefully learn the Gospel. Let him continue in humble prayer. We are molested not by puny foes, but by mighty ones, foes who never grow tired of warring against us. These, our enemies, are many: Our own flesh, the world, the Law, sin, death, the wrath and judgment of God, and the devil himself. The arguments which the false apostles advanced impress people to this day.” source
