It is implied that the weeping and gnashing of teeth will go on for a bit until they are no more.
I am reminded of being with someone who thought they would die.
When they got better, there was pure terror and relief in their attitude.
All they thought of was being dominant in life and succeeding, and once on the slippery
slopp all was lost. Imagine such a person meeting God and seeing their whole life was
founded on putting others down and gaining respect.
What is left when you meet God, and everything in ones heart falls away? Weeping and
gnashing teeth. For me this is like a nervous breakdown, when all defences have gone,
who one is is totally exposed and nothing adds up. No escape, no compromise, no finding
safety or reassurance, for the source of love and reassurance is actually ones enemy.
