There is a LOT going on in this chapter of Revelation, so it might be helpful to situate ourselves somewhat in the position of its original audience. The Romans had probably already destroyed Jerusalem and the temple prior to this book being written, and that time was full of intense suffering. The suffering of God’s people does not go unnoticed by him, and worship can still emerge from the madness his people encounter. We do see his chosen ones caught up with him as a precious possession, worship continuing past the madness, and God reigning supreme. If you had the destruction of your religious center in your memory, this would have been a very good thing to know.
