Few archaeological sites offer as rich a field of discovery as Tel Megiddo. Occupied for thousands of years until the fifth century CE, Megiddo was once an important Canaanite city-state and then a key trading center in the ancient Kingdom of Israel. Occupying a strategic crossroads situated at the juncture of the main road from Egypt to Mesopotamia and from Phoenicia to Samaria and Jerusalem it has yielded invaluable information about daily life in ancient Canaan and Israel.
Megiddo was also the site of several major battles, from the time of ancient Egypt through the height of Judean civilization in the time of King Josiah, to the modern WWI battle between British and Ottoman forces. Here, two kings of Judah lost their lives, one fleeing south from the wrath of Jehu of Israel, the other boldly (and unwisely) confronting Neccho II of Egypt.
The death of Josiah at Megiddo marked a turning point in providential history, after which, from the standpoint of the biblical writers, the doom of the Kingdom of Judah was virtually sealed. From the standpoint of the Divine Principle, too, the providence of restoration during the period of the Divided Kingdoms by this time was in deep trouble, and the period of Babylonian captivity loomed as almost inevitable.
While many Christians look to the Battle of Armageddon as a literal event that may even play out at or near Megiddo, Unificationists see it as a symbolic confrontation of the forces of good and evil. Rather than a physical war in the Middle East, it represents the destruction of the satanic sovereignty, carried out not with physical weapons but with the "double-edged sword" of truth. Indeed, the normal Unificationist interpretation of the Book of Revelation is that the Marriage Supper of the Lamb already happened in 1960. If so, then the Battle of Armageddon, too, must have already occurred.
Megiddo itself thus remains an archaeological treasure, which deserves to be appreciated for more what it can tell us about our past than what events will unfold there in the future.
