How important is it to defend the gospel against distortions and redefinitions? Is it too far fetched to think that servants of Satan could disguise themselves as Christian leaders? Why are warnings against false teachers fairly common in the New Testament? What is the best way to prepare ourselves to be discerning as we can be exposed to so many voices claiming to speak truth? Out of love for Christ and his Bride, Paul here takes aim at those who would preach "another Jesus" (11:4).
