Jude follows this up by quoting from a prophecy of Enoch, which, although not recorded in Old Testament history, was plainly of divine origin.  Enoch, the seventh from Adam, prophesied of the coming of Christ, and the dreadful vengeance which He will exact against all His foes.  He will execute judgment upon all, separating the righteous from among the wicked, and pronouncing the final sentence upon every soul of man.  He will convince all the ungodly of the ungodly deeds that they have committed, so that their mouths may be stopped.  Those who boasted the loudest in this world of their perversity will find their lips utterly shut when the Lord Christ confronts them with their terrible guilt.  There will be no more hard speeches against the holy God and His humble people emanating from them, for the only confession they will be able to make is that Jesus Christ is Lord, to the glory of God the Father.

This may look on the surface like a general prophecy against all the wicked of the world, which surely is not an unfair application.  Yet it is plain from the context that Jude intends it primarily against the ungodly teachers, who have a name to live, and yet are dead.  They make a profession of godliness, yet deny the power thereof by their licentious lives and antinomian doctrine.  Such, Enoch prophesied, will be on the receiving end of Christ’s curse and condemnation at the last day.  How important does this make it that we be faithful and sincere with the word of God, not perverting it or ever using as a license for sin, but teaching men obedience to every commandment of our God and Saviour!
