Is the Book of Revelation Preaching?

When we planted Emmaus 11 years ago, this is one of the issues we had to study as an eldership and it's one of the things we had to teach to the congregation. I went from being rather tired and disinterested about this subject to thinking to myself, "This preaches" The Lord wants us to know with the saints through the ages that he's on the throne. When he returns, all things will be put under his feet.
