With Jude and 2 Pet 1-3, you find them telling us to contend for the faith, and that no prophecy is of any private interpretation, all the while they are quoting Pseudepigrapha and Apocryphal Books (Enoch, Assumption of Moses and Ahikar). And then indicating in the latter times, believers will be sensual(selfish) and walking after their own \""lusts\"" (desires of any sort that are bad).
