They ARE waking up. I have just come across someone in my congregation who is awake. I know two people in another congregation who are PIMO who are in my social circle. I know of another guy who has faded recently and is openly expressing doubts in the next town. That's not to mention the people I know in the local area who are on the board here.
I also know of several people who will express certain doubts and questions even if they are not properly awake.
I bet there are more people that we think that are teetering on the edge. I am confident that there are more people questioning, awakening and even actively fading or leaving than we think. Perhaps not enough to form a critical mass of discontent but I am sure I know people that I have no idea are awake just as they have no idea about me.
It's not all bad news!
