Doesn't he read the Watchtower?
Nope! He doesn't know half of what this religion teaches. I suspect a lot of people don't keep up with a ton of stuff because it always changes. They hold onto a couple of scriptures like Matt. 24:14 and convince themselves that it has to be the truth because of that and have no idea of what is going on everywhere else...
Right now he doesn't do to much with the religion. Just attends most meetings. Although we missed both mtgs this week.
I suspect he is going to be ultra spiritual that year and then when it doesn't come he will probably lose interest in the truth altogether or just do bare minimum like he has been to keep his connections with his friends.
