7 When the thousand years are ended, Satan will be set free from his prison 8 and will go out to deceive the nations which are in the four corners of the earth, Gog and Magog, to gather them for battle. Their number is like the sand of the sea.
Think things are bad now? In this Scripture, Jesus has returned, and rules with the martyred saints for 1000 years in perfect justice and peace. Even after this, when Satan is released, he is able to raise an innumerable army from the nations, bent on wiping God's people--Israel of the Promise (Romans 9:6-9)--off the face of the Earth.
The outcome is inevitable. No power can overcome the One who spoke all of Creation into being. The price of this evil is unthinkable--eternal separation from the Creator, God.
