The general epistle of Jude was written as a warning against certain nominal Christians who threatened to undermine and destroy the fellowship of believers by their immoral character and conduct. Those who follow intheir path can be certain of God’s judgment.
Indeed, the Old Testament bears witness to six judgments of God upon just such sins as these persons practice- 5:11. As if to emphasize their ripeness for God’s wrath, Jude who is also a brother of our LORD Jesus adds a twelve-fold description of their guilt-12-16. In contrast to the destructive and worldly attitudes of the false teachers, believers are to show a constructive and spiritual love. Remembering the mercy of Christ towards them, they are also to show mercy towards those engulfed in these evils. Perhaps some will thus be saved-12-13.
The beautiful doxology -24-25 is especially appropriate for those in great temptation. In addition to his use of Old Testament, Jude shows knowledge of current Jewish tradition in 9 and 14 although not to the Old Testament, are found in other Jewish writing of his day. The epistle bears a particular close relationship to the second epistle of Peter, and it is possible that both letters were destined for the same group of Christians. Although a number of scholars believe that, II Peter made use of Jude, it is more likely the earlier of the two. The evils which II Peter 2:1 and3:3 predicts are described in Jude 4, 18-19 as having come in accordance with the apostolic prophesy made to them.
