The time period of the 4 horses and riders and consequently all 6 seals Y’shua opened and brought His prophesied prophetic judgments upon the Pagan Roman Empire took over 300 years to be fulfilled and established in world history. We have over 1700 more years to interpret from this book, and hopefully by the time we come to our current place in the book of revelation you will see how ludicrous the idea is that this whole book could be repeated and fulfilled again in as little as 3 ½ years.
