We have already seen Paul, Peter and John provide inspired warnings against false teachers. And now we see Jude, the half-brother of Jesus continue to warn believers of these men who will arise in their midst. And in my mind Jude’s words describe the true nature of these false teachers very well.
Jude:12 These people are blemishes at your love feasts, eating with you without the slightest qualm—shepherds who feed only themselves. They are clouds without rain, blown along by the wind; autumn trees, without fruit and uprooted—twice dead. 13 They are wild waves of the sea, foaming up their shame; wandering stars, for whom blackest darkness has been reserved forever.
