Read this before Teaching Revelation (or other Apocalyptic texts)
Interpreting, preaching, and teaching through books like Revelation, Zechariah, Ezekiel, and the latter half of Daniel can be a bit intimidating. There are some great technical resources out there for better understanding these apocalyptic texts (pride of place goes to Collins, The Apocalyptic Imagination), but most of these are pretty technical.
There is, however, a very short, readable, and practical resource that will help anyone process this important and powerful genre, and it’s freely available: David Helm’s An Approach to Apocalyptic Literature: A Primer for Preachers. Whether you’re an expert on this type of thing, or quite intimidated by it, this is a helpful little guide.
