....he started to talk about 1975 and how people were selfish and thought of a date...
LOL -- Isn't that the ultimate 'bait and switch'?
They go to people's doors, and ask them if they're tired of sickness, pain and sorrow. If the person says, 'Yes', they show them pictures of a wonderful paradise and say, 'The Bible promises that this will be here very soon --- In your lifetime! Would you like to know more?'
Fast forward 30, or 40 years and anyone who's having trouble over the fact that the 'carrot' never gets any closer is selfish. --Just like those people in 1975.
