I remember seeing an Our Kingdom Ministry prompt where it encouraged Witnesses to explain what you just described, that Jesus would judge them worthy of survival or not depending on how they responded to the door-to-door preaching. Can you just imagine going up to someone and saying that on their porch or on the street.
'Good morning, how you doing today? You better listen up and do what I tell you cuz if you don't Gods gonna kill you any day now.'
It's such an obvious threat. That's what it.
