The prophet Zechariah wants us to remember all the bloodshed, and the tears that resulted from it, from Zechariah 12:10–11.
> Zechariah 12:10–11
“And I will pour out on the house of David and the inhabitants of Jerusalem a spirit of grace and supplication. They will look on me, the one they have pierced, and they will mourn for him as one mourns for an only child and grieve bitterly for him as one grieves for a firstborn son. On that day the weeping in Jerusalem will be as great as the weeping of Hadad Rimmon in the plain of Megiddo.”
The prophet looks forward to a time when God’s people will turn back to him in repentance and a return to their covenant with Him with weeping that is so deep that it recalls the weeping associated with this place.
> Zechariah 13:1
“On that day a fountain will be opened to the house of David and the inhabitants of Jerusalem, to cleanse them from sin and impurity.”
Megiddo teaches us that the most important battles are not fought with bombs, or guns, or swords, or even sticks and stones. The most important battles are fought with ideas; and the most powerful victories are won by laying down one’s own life, not taking someone else’s. When we are at this place, it should teach us that Jesus won his most important battle by taking the hit, not making one. We must fight His war, but we must do it with His weapons in His way.
And so, the lesson of Megiddo is not that “life is a battle, but God wins.” Rather, it is that the discerning among His followers will choose their battles, and their battlefields, wisely.
