Book of enoch (Digireads.com)

"As the 'Book of Enoch' is, in some respects, the most notable extant apocalyptic work outside the canonical Scriptures, it will not be inappropriate to offer a few remarks here on the Apocalyptic Literature generally. Hope is, indeed, the main underlying motive-power which prompted the writers of the Apocalypses. And this hope is the more intensive and ardent in that it shines forth from a background which is dark with despair; for the Apocalyptists despaired of the world in which they lived, a world in which the godly were of no account, while the wicked seemed too often triumphant and prosperous. With evil everywhere around, the Apocalyptists saw no hope for the world as it was; for such a world there was no remedy, only destruction; if the good were ever to triumph it must be in a new world."-From the Introduction.
