And I saw three unclean spirits like frogs coming out of the mouth of the dragon, out of the mouth of the beast, and out of the mouth of the false prophet. 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.
As we saw in Revelation 12:9-10 , the dragon is Satan the devil. The beast is a great governmental ruler based in Europe; and the false prophet, a great religious leader. This passage shows that the demonic world is behind these end-time powers and will use miraculous signs to convince leaders throughout the world to gather in the Holy Land to oppose the returning Jesus Christ. They will gather at Armageddon and will then fight against Christ at Jerusalem ( Revelation 16:16 ; Zechariah 14:2-4).
Thankfully, all the armies of the earth are just a drop in the bucket to God, and Jesus Christ will easily defeat Satan’s last-gasp attempt to destroy mankind and God’s plan. Then Christ will establish the Kingdom of God and finally bring real peace to this world.
