In Volume IV the author, Evelyn Theresa Watson, compares the Revelator's words to scriptural and gospel prophecy verifying the doctrinal mystery and miracle that lie behind the religious warfare of past and present ages.
Her commentary presents THE REVELATION OF ST. JOHN THE DIVINE as a treatise on the life and time of Jesus Christ as the messenger of the messianic message unto the seven churches. She attests to the Revelator's seven visions of revealed prophecy which retell the previous two thousand years of unfulfilled scriptural prophecy and foretell one hundred years of fulfilled gospel prophecy. The author correlates these two time periods to the nineteen hundred years of biblical prophecy that followed. The beginning of the twenty-first century marks the end times of the Bible's historical phases of prophetic teaching.
