They have no date to look at - not that we're supposed to speculate. But, when you're on a treadmill of 5 weekly meetings a week, field service on the weekends, and making yourself available for those return visits and bible studies, it can all get too much - so what do you do? Hope the world will end soon, calculate your own Armaggedon dates and wish it was all over. They can't do that anymore.
Could you imagine running on a treadmill with a personal trainer that keeps saying: You can stop in just a moment... any second now.. soon... very soon... almost there...
but you never actually get to stop!
