"AND YE SHALL HEAR OF WARS AND RUMORS OF WARS. SEE THAT YE BE NOT TROUBLED, FOR ALL THESE THINGS MUST COME TO PASS, BUT THE END IS NOT YET....FOR NATION SHALL RISE AGAINST NATION AND KINGDOM AGAINST KINGDOM...THEN SHALL THEY DELIVER YOU UP TO BE AFFLICTED AND SHALL PUT YOU TO DEATH...BUT HE THAT SHALL ENDURE UNTO THE END, HE SHALL BE SAVED." - MATTHEW 24:6-13
