Many of us have most likely had to listen to a talk that has a statement like this -
" Imagine when you are in the new system in a beautiful place, you will be able to look back and think ' Wow! I had a good share in the preaching work and was part of fulfilling Mat 24:14"
So instead of living in the moment, the witnesses project themselves into the future and then imagine themselves looking back to the past.
That's enough to screw with anybodys mind!
In my experience, they live in the past and the future, but not in the present. A fertile ground for mental illness.
