A key

False teachers ALWAYS appeal to your flesh, in some form or other: they appeal to your ego, your pride, your intellectual pride, your spiritual pride, feelings of superiority or elitism, to your covetousness, to any sinful desire to justify indulging in unlawful liberties. The key is this: they speak only for their own benefit, and their appeal is in the same order, appealing to those who only seek their own benefit.
