The heart of this text is about the prophetic signs of the Second Coming of Jesus Christ. After the birth of Jesus, and the scattering of the Jewish people, the prophetic signs of Jesus' Second Coming were few and far between. It was a long time between events, that signal the Second Coming of Jesus.
The birth of the Holy Roman Empire was one of the first big prophetic fulfillment of the Second Coming of Jesus Christ to the earth. The birth of the Holy Roman Empire occurred on 25 December 800 AD.
This book continues discussing about other prophetic signs which have been fulfilled and how prophetic sign fulfillment has accelerated since World War 1.
