False Teachers Are Deceptive
False teachers are deceptive. They do not announce themselves as false teachers, but proclaim themselves angels of light, people who have access to wisdom others have missed or misplaced. As Denny Burk says, “False teachers typically won’t show up to your church wearing a sandwich board saying, ‘I am a false teacher’.” Instead they begin within the bounds of orthodoxy and announce themselves only slowly and through their subtly-twisted doctrine. They turn away from orthodoxy one step at a time rather than all at once.
False Teachers Are Dangerous
False teachers are dangerous, and part of what makes them so dangerous is that they will affirm so much that is good and true. They will not deny all of the doctrines upon which the Christian faith stands or falls, but only select parts of it. They draw in the unsuspecting with all they affirm and only later destroy them with all they deny. There is an important lesson: We only know a person when we understand both what he affirms and what he denies.
False Teachers Give People What They Want
As Paul wrote his final letter to Timothy he warned that the time was coming when people would not endure sound teaching (and hence, sound teachers) but instead they would have itching ears and demand teachers who would satisfy this itch. False teachers do this very thing. Their concern is not for what people truly need, but for what people want. The concern of the Christian is the exact opposite—the gospel does not address what we want, but what we need!
False Teachers Are Not Innocent
False teachers know they are false teachers. This may not be true all the time, and perhaps some false teachers deceive themselves before they deceive others. But I believe most know who and what they are; in fact, I believe most know and delight in who and what they are. They are not naive people who have taken a wrong turn in their theology, but evil people who are out to destroy others. Their attack on truth is far more brazen than we may like to think.
False Teachers Cannot Tolerate the Gospel
False teachers simply cannot tolerate the gospel. At some level and in some way, they will always add to or subtract from the pure and sweet gospel of salvation by grace alone through faith alone in Christ alone. They may affirm the Trinity or inerrancy or the deity of Jesus Christ, but they will never fully affirm the gospel of the Bible.
