"Armageddon, (probably Hebrew: “Hill of Megiddo”), in the New Testament, place where the kings of the earth under demonic leadership will wage war on the forces of God at the end of history."

"The battle of Armageddon refers to the final war between human governments and God. These governments and their supporters oppose God even now by refusing to submit to his rulership. (Psalm 2:2) The battle of Armageddon will bring human rulership to an end.—Daniel 2:44.
The word “Armageddon” occurs only once in the Bible, at Revelation 16:16. Prophetically, Revelation shows that at “the place that is called in Hebrew Armageddon,” “the kings of the entire inhabited earth” will be gathered “together to the war of the great day of God the Almighty.”—Revelation 16:14.
Who will fight at Armageddon? Jesus Christ will lead a heavenly army to victory over God’s enemies. (Revelation 19:11-16, 19-21) These enemies include those who oppose God’s authority and who treat God with contempt.—Ezekiel 39:7.
Will Armageddon literally be fought in the Middle East? No. Rather than being restricted to one area, the battle of Armageddon will encompass the whole earth."

"53Thinkest thou that I cannot now pray to my Father, and he shall presently give me more than twelve legions of angels?"

"41The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity; 42And shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth. 43Then shall the righteous shine forth as the sun in the kingdom of their Father. Who hath ears to hear, let him hear."

"Many correctly view Armageddon as the gathering place of the Antichrist and his armies prior to the Glorious Appearing of Jesus Christ, but they misinterpret the motive of this gathering.
A commonly held belief is that these armies gather together at or near Armageddon in order to do battle with each other, or to annihilate the Jewish people. Then, only through the physical intervention of Jesus Christ is humanity saved from either destroying all life or the Jewish people.
But neither of these motives is correct. The Bible clearly states why these armies gather together at Armageddon, and once we realize why, it's easy to see why most Christians find it difficult to believe.
What Does the Bible Say?
The biblical concept of Armageddon is first introduced by name in the Book of Revelation:
"**And they gathered all the rulers and their armies to a place called Armageddon** in Hebrew." Revelation 16:16 (NLT)"

"The Destruction of Jerusalem
(Matthew 24:15-25; Mark 13:14-23)
20And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh. 21Then let them which are in Judaea flee to the mountains; and let them which are in the midst of it depart out; and let not them that are in the countries enter thereinto. 22For these be the days of vengeance, that all things which are written may be fulfilled. 23But woe unto them that are with child, and to them that give suck, in those days! for there shall be great distress in the land, and wrath upon this people. 24And they shall fall by the edge of the sword, and shall be led away captive into all nations: and Jerusalem shall be trodden down of the Gentiles, until the times of the Gentiles be fulfilled."

"The millennial kingdom is the title given to the 1,000-year reign of Jesus Christ on the earth. Some seek to interpret the 1,000 years in an allegorical manner. They understand the 1,000 years as merely a figurative way of saying “a long period of time,” not a literal, physical reign of Jesus Christ on the earth. However, six times in Revelation 20:2-7, the millennial kingdom is specifically said to be 1,000 years in length. If God wished to communicate “a long period of time,” He could have easily done so without explicitly and repeatedly mentioning an exact time frame."

"26And he that overcometh, and keepeth my works unto the end, to him will I give power over the nations: 27And he shall rule them with a rod of iron; as the vessels of a potter shall they be broken to shivers: even as I received of my Father."

"5And she brought forth a man child, who was to rule all nations with a rod of iron: and her child was caught up unto God, and to his throne."

"the Mahdi is not mentioned in the Qur’an and his mention in the Sunnah is less substantiated and his role is much less central than those of Jesus as a portent of the Last Day. The Mahdi will be only such a just ruler who will rule towards the end of the world and he will be one of Jesus’ aides.
It is noteworthy that Muslims believe that a Jewish messiah will emerge towards the end of the world. Nevertheless, they believe that he is not the Christ but rather the Antichrist who will be killed by Jesus upon his descent."
