The book of Revelation is a book full of symbolism, taken in large part from the Old Testament. In the book of Ezekiel, the Lord told the prophet Ezekiel to prophesy against Gog, from the land of Magog, enemies of Israel and of God. Now, in Revelation 20, Gog and Magog are the personification of God’s enemies. The scenario is that the saved are with God in the New Jerusalem, which has come down from heaven to earth, and that the wicked, who had all been dead, are resurrected to face God in the final judgment. Satan, who had nobody to tempt for a thousand years, suddenly has all those who from creation to the end of time, rejected God’s offer of salvation, and he rallies them all in one great effort to take the New Jerusalem by force. These people, all of the wicked of all ages, are now called Gog and Magog, symbolizing God’s enemies from all of earth’s population.

Ezekiel 38:2   “Son of man, set your face against Gog, of the land of Magog, the prince of Rosh, Meshech, and Tubal, and prophesy against him …”

Revelation 20     ⁷ Now when the thousand years have expired, Satan will be released 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 together to battle, whose number is as the sand of the sea. ⁹ They went up on the breadth of the earth and surrounded the camp of the saints and the beloved city. And fire came down from God out of heaven and devoured them.

People have often wondered where the countries or people of Gog and Magog are, who are to be gathered by Satan for the last great battle. They are not from any specific nation or country, but are just symbolic of all the wicked who throughout earth’s history had rejected God’s mercy. 

I hope that this makes sense to you. God bless!
