We have many older brothers and sisters in our congregation, and surely the same in many congregations all around the world.
What will be the reaction in the congregations when all these older ones, who were sure they wouldn't die before the end, pass away and leave a vacuum in the congregation.
I don't wish these older brothers and sisters harm, but eventually they will be too old to follow and they will die away.
It won't be the same anymore, when they see these old pillars who stood so faithfully crumble due to old age.
