It's only a couple of years away now and what a headache it must present to the GB - providing they have given it much thought already. There probably is no elegant way of presenting the hundred year long failure of the end to come; the fact that the "short period of time" of Satan being cast down to the earth has now stretched beyond any credibility. But they have to deal with it one way or another. What do you think is most likely:
1. Completely ignore it, don't mention it or acknowledge the anniversary at all.
2. A very short mention in a low key artilce about the anniversary just to draw a line under it without drawing too much attention.
3. Completely own the anniversary, make a big deal about it, and pretend like it is a great reminder that we are living in the time of the end with no hint of embarrassment at all.
4. Finally call time on the 1914 and drop it as having no scriptural, historical or rational basis.
5. Promote a new endtime prediction involving 1914 to give new impetus. (Such as 2034 because it is 1914 + 120 years "like the days of Noah")
6. Or can you think of some other strategy they might adopt?
