Will this video explain how they connect 1914 to 1919? You would be lucky to find a single publisher in any typical congregation who could explain THAT!
Or how about this scenario built in to the demonstration:
Householder: "Ok. So if Jesus was enthroned as King in 1914 then his thousand year reign must have started then, right? (Rev 20:4)"
JW: "Umm, no. The thousand year reign doesn't start until after Armageddon."
Householder: "Huh? But if Jesus was made King in 1914 he must have sat on his throne and started ruling then?"
JW: "Errrmm, yes he did, but his thousand year reign is only when he effectively starts to reign over the whole earth?"
Householder: "Oh. So what has Jesus been reigning over since 1914?
JW: "Aaah...technically nothing really, except possibly JW's. He did boot Satan and the demons out of heaven a few years later though in 1918."
Householder: "What? So you're saying Jesus became King in 1914 and ruling since then but hasn't been reigning over anything but apparently your organisation? Where did Jesus say that?"
JW: "Ummmm...here in Matthew 24:3. It says "What will be the sign of your presence and pf the conclusion of the system of things". You see, Jesus has been present as King since 1914 then all the wars, famines, earthquakes, etc, happened to prove it."
Householder: "My Bible says 'coming' not 'presence'. So does that mean Jesus came in 1914?
JW: "No, his second coming is in the future still, but he became present in 1914."
Householder: "Huh? How could Jesus be present unless he first comes? It's like saying I'm present in this house but I've never come into it?"
JW just stares blankly....
Householder: "And Matthew 24:3 doesn't say anything about his being king in 1914? Here in Matthew 25 it says Jesus sits on his glorious throne and separates the sheep and goats - so you must mean that happened in 1914 right?"
JW (squirming and feeling quite embarrassed now): "Errm, no, that is actually a future event that hasn't happened yet. Jesus sat on a different throne in 1914, a judgement throne."
Householder: "Look, this really does seem a bit queer to me and hardly convincing. Sorry it's been interesting chatting but I just don't think I'm interested, bye."
(JW walks off disconsolately scratching his head feeling like a bit of a dork.)
