The apocalyptic genre in the NT is found in the Book of Revelation. A lot of confusion exists about how to interpret this book because many don’t understand the importance of genre in the approach to a book of the bible. Apocalyptic is a genre which can be defined as revelatory literature which tells a story, given from a heavenly being (often an angel) to a human being, in which a transcendent reality dealing with salvation in end times and involving heaven is portrayed (modified from Bauckham).
Keeping this definition in mind, it is helpful to remember much of Revelation is symbolic. Though Revelation is probably the hardest book of the bible to understand, we can fathom most of what is communicated by knowing that it is filled with OT allusions. Many of these are from Daniel, Ezekiel, Zechariah, Isaiah, etc. Also, we should bear in mind that Revelation is written as an exhortation to the church to endure suffering, despite spiritual warfare, and to remain faithful witnesses. Despite judgments being displayed, God uses his church to change hearts and to bring about a great salvation among mankind. Jesus is returning, so those on his side will be ultimately victorious, though they will have to suffer in the interim.
