There's symbolism in the use of the word - is what that quote is expressing (I believe, I didn't write that, I merely shared it).
From another author:
It needs to be recognized that in speaking of Armageddon, or the mountain of Megiddo, the apostle John is not alluding to a literal place. The use of geographical points to emphasize spiritual truths is a common biblical phenomenon. Consider, for example, the word “hell” (Grk.
gehenna). The Greek
gehenna relates to the Hebrew
gehinnom, which was the Valley of Hinnom just south of Jerusalem. In Old Testament times, when the Jews became involved in idolatry, they offered their children as burnt sacrifices there (2 Kgs. 16:3; 21:6). Later, because of its connection with pain, weeping, and burning (Hinnom became the city dump, continuously on fire),
gehenna became a symbol for the final punishment of hell. Certainly it would be absurd to contend that on the Day of Judgment, the wicked will be cast into the literal Valley of Hinnom near Jerusalem.
Similarly, and characteristically, John, in the Revelation, frequently uses places as symbols for concepts. So Zion (14:1), or Jerusalem (21:2), are symbols of God’s spiritual city, the church. Babylon signifies apostasy, and all that is opposed to God (14:8); Egypt and Sodom (11:8) represent oppression and wickedness; the Euphrates (16:12) was symbolic of the point of origin of (spiritual) Israel’s enemies, etc. It is within such a reference frame that “mountain of Megiddo” likewise is used.
The history of Megiddo is quite interesting. It is the earth’s most famous battle-field. J.L. Hurlbut declared that “more battles have been fought on this plain than on any other in the world” (1954, p. 15). A number of famous Old Testament conflicts occurred there. It was renowned for the victories of Deborah and Barak over the Canaanites (Jdg. 4:15), and of Gideon over the Midianites (Jdg. 7). Josiah was also killed in battle there (2 Kgs. 23:29).
“It is not unlikely,” says Morris, “that the deliverance under Deborah is regarded as setting the pattern. Then Sisera had 900 chariots of iron (Jdg. 4:13), but in Israel there was scarce a shield or spear among 40,000 (Jdg. 5:8). Israel’s position appeared completely hopeless. But when the battle was joined, ‘the Lord routed Sisera and all his chariots and all his army’ (Jdg. 4:15 RSV). So will it be at the last day. However strong the forces of evil may appear, and however hopeless the position of those of good, God will win the victory. He will resoundingly overthrow the evil” (p. 200). And so, “The old battleground becomes the symbol of the decisive struggle, it is raised in meaning: it is a type, not a locality” (Carpenter, p. 609).
While
some would identify the pouring out of God’s wrath in Revelation 16 (including Armageddon) with the destruction of Jerusalem, or perhaps with the cessation of Roman persecution at the time of Constantine, it is more likely that
Armageddon is used as a symbol of “the final overthrow of all the forces of evil by an almighty God” (Morris, p. 192).
Professor Russell B. Jones says: “We seem to be on safe ground when we understand the ancient battle-field at Megiddo as a type of the final stand of the enemies of righteousness against the Lord at His appearing” (p. 88). Again,
Mounce notes: “... Har-Magedon is symbolic of the final overthrow of all the forces of evil by the might and power of God” (p. 302). ~ Armageddon: The Next of the "Left-Behind" Series
