@wizzstick,
Nice one.
Probably some day in future, they will start this line of reasoning:
We know that the 'days' in Genesis creation account - although each clearly divided by a single night from the previous day - lasted many thousands of years each. Likewise the 'last days' can last many thousands of years each.
In the past some have jumped to the conclusion that Armageddon would come during their generation. However, when Jesus spoke about this generation he clearly referred to the generation that would be alive when Armageddon starts.
Don't blame Jehovah for tricking you again. Just be patient, happy with the increased understanding He gives us. Oh and fork over your money.
