Paul warned that Satan's ministers appear as ministers of righteousness, not as open enemies. This study examines why the counterfeit stands inside the Christian column rather than beside it, why sincerity, results and personal godliness cannot test a teacher, and what Paul actually gives the Body to test him with.

Satan is one adversary, but he does not wage one war. Toward Israel's remnant he is the accuser and the devourer, assaulting a salvation kept by endurance. Toward the Body of Christ he can only deceive, for our standing is sealed beyond his reach. Right division belongs to the doctrine of the devil no less than to the doctrine of grace.
