The end of days of this earth, the last years of time, will be known by the indisputable events taking shape when there will come in that time a rise to power of one ruler over this whole earth. When this event comes to pass, the last years on this earth will begin to count down to the end of time (Revelation 13-16-17, 14:11. 17:11).
Since the beginning of time, there have been to date six worldly kingdoms on this earth headed by six kings: Egypt (1 Kings 14:25–26), Assyria (2 Kings 17:5–6), Babylon (2 Kings 25:1, 8–9), Persia (2 Chronicles 36:23), Greece (Daniel 8:21, 11:2), and Rome (John 19:15). In John’s vision of the end of time, he revealed these world kingdoms when he saw the kings: “And there are seven kings: five are fallen, and one is” (Revelation 17:10). There is one last world kingdom headed by two wicked kings to come at the end of time (Daniel 8:23–24) (Daniel 11:36–37); the eighth being the devil, aka, Satan. “And the beast that was, and is not, even he is the eighth, and is of the seven, and goeth into perdition” (Revelation 17:11).
“As a roaring lion, and a ranging bear; so is a wicked ruler over the poor people” (Proverbs 28:15).
