Robin Webber provides much excellent insight into how to understand the book of Revelation. Speaking on the mark of the beast and the number of the beast, Webber notes that it is important to be loud where God is loud and quiet where God is quiet, and be careful in between. The book of Revelation is a balance between being literal and symbolic; type and antitype, with layered duality, containing prophecy and wisdom. Also, God gives us enough to comprehend what we need to comprehend at any given time. There are two sides: Satan and the people he uses vs. God’s people; Jerusalem above vs. Babylon below; destruction vs. salvation.
