That was the reasoning in a recent public talk at my hall.
Namely: If the end of the world happened in 1975, then loads of people who had not yet converted or been born would have been destroyed, or never existed, so therefore we should be happy that Yahweh was patient and armageddon hasn't come yet.
Anyone else see like 5 blaringly horrible problems with this reasoning?
#1 That will never stop being true! There will always be possible future converts or the possibility that someone bad is going to give birth to a nice person at some point in the future.
#2 If armageddon isn't going to come until EVERY possible convert has converted, then there's really no hurry. You can take all the time you want to preach, nobody is going to miss out because of it.
#3 The population of the earth in 1975 was only a little over 4 billion. Meaning only 4 billion people would have died in armageddon. Now there's almost 7 billion. So because he waited he's gonna have to kill an extra 3 billion or so people.
#4 What about all the babies that WOULD have been born in paradise if armageddon happened in 1975 but will now never get a chance to exist because god took his time? Are they worth less than the imperfect babies that MAYBE get saved when armageddon doesn't happen? (Yeah that was a coherent question, read it again!)
#5 Something else I thought of when I started this rant but now I forget.
But the worst part is: Everyone in the audience is just nodding their heads like: "oh that makes so much sense, I'm glad he's so loving and patient" but then 10 minutes later they're gonna be all like: "the end is SO close we have to go preach and save LIVES"
