Revelation 16

And they gathered them together to the place called in Hebrew, Armageddon. v.16

Read chapter 16
Armageddon.  It's not talking about the 1998 movie with Ben Affleck and Bruce Willis where the worlds about to end being destroyed by a meteor.  There's a lot of superstition about what Armageddon is.  Many think it a giant cataclysmic battle that takes place at the end of the world.  For those who have no hope in eternity with Christ, this world seems like that's all there is and an end will eventually come.  But for those that put their faith in Jesus Christ, Armageddon is not the end of the world.  Now the battle of Armageddon is commonly talked about but there's no indication there's a battle here, it's more where they camp out before battle.  Who's "they"?  It's Satan and his spirit demons. Armageddon means the "hill of crowds." Armageddon is where they gather the kings of the world to prepare for battle as we read in verse fourteen, " For they are spirits of demons, performing signs, which go out to the kings of the earth and of the whole world, to gather them to the battle of that great day of God Almighty."  In 2 Kings 23 we read of the battle at Armageddon in the Old Testament under Josiah, but this doesn't seem to be the same in this future tribulation time. And this battle between those of Satan and those of God isn't really going to be a battle but more a slaughter as nothing is a fight to God- He always wins triumphantly and will give His people supernatural ability to power over these demons forces.
So when you think of Armageddon, don't think of the movie or the end of the world, but think of how it's the beginning of evils end.
