Aside from the fact that this prophecy is totally made up, it's linked to a prophecy Jesus gave at Luke 21:24:
And they will fall by the edge of the sword and be led captive into all the nations; and Jerusalem will be trampled on by the nations until the appointed times of the nations are fulfilled.
Now, let's read it in context (vs. 20-24):
However, when you see Jerusalem surrounded by encamped armies, then know that the desolating of her has drawn near. Then let those in Ju·de′a begin fleeing to the mountains, let those in the midst of her leave, and let those in the countryside not enter into her, because these are days for meting out justice in order that all the things written may be fulfilled. Woe to the pregnant women and those nursing a baby in those days! For there will be great distress on the land and wrath against this people. And they will fall by the edge of the sword and be led captive into all the nations; and Jerusalem will be trampled on by the nations until the appointed times of the nations are fulfilled.
Hang on. Even more context (vs. 5-7):
Later, when some were speaking about the temple, how it was adorned with fine stones and dedicated things, he said: “As for these things that you now see, the days will come when not a stone will be left upon a stone and not be thrown down.” Then they questioned him, saying: “Teacher, when will these things actually be, and what will be the sign when these things are to occur?
So, this is a prophecy about the last days, the parallel to Matthew 24. If the last days BEGAN in 1914, how could this part of the prophecy END in 1914?
Also, how could this prophecy be talking about something in the past from Jesus' perspective?
And they will fall by the edge of the sword and be led captive into all the nations; and Jerusalem will be trampled on by the nations until the appointed times of the nations are fulfilled.
I'm no English major, but the phrase "will be" indicates something in the future, not in the past.
Wow, oh, wow, oh, wow! This whole prophecy is debunked so many different ways it's absolutely stupid for WTBTS to keep propogating it!
