Match of the Ages

At the end of the eleventh chapter of Revelation, John is concluding his interlude about the angel and the little book and the measuring of the temple and the two witnesses.  The seventh angel sounds the seventh trumpet introducing the third woe, which does not immediately fall upon men. Instead, loud voices in heaven announce the coming of the end, which really focuses on the central theme of the book of Revelation: the establishment of the Kingdom of God on the earth.
