Objection is often raised—even by some sound in the faith—regarding exposure of error as being entirely negative and of no real edification. Of late, the hue and cry has been against any and all negative teaching. But the brethren who assume this attitude forget that a large part of the New Testament, both of the teaching of our blessed Lord himself and the writings of the apostles, is made up of this very character of ministry—namely, showing the satanic origin and, therefore, the unsettling results of the propagation of erroneous systems which Peter, in his second epistle, so definitely refers to as “damnable heresies.”
