Why some won't leave the Watchtower........
In no particular order...
1... Inertia
2... Attitudes , lies and lifestyles of apostates / ex-witnesses
3... Lack of any viable , sensible & realistic alternative form of "Christian" worship that matches the biblical pattern.
4... Possibility (though faint) that JWs might be right after all. (Say there is a 10% probability that this is the true religion - what is P10 of everlasting life with perfect health in a paradise earth? Or P1? P1 of infinity is infinity. People buy a lottery ticket on a 1 in 13 million chance.)
5... Family ties
6... Business interests and contacts
7... Purpose and fulfillment through WTS activities (eg Quick builds , organising & preparing meeting parts etc)
8... Social ties - football after the group , BBQs at the weekend , coffee and doughnuts after Saturday ministry.
9.. All those sexy babes / guys at assemblies (delete as appropriate - age & marital status dependant). (Where do they go for the rest of the year? When I was a single guy , I used to literally walk around with my tongue hanging out.)
10... Access to free janitorial supplies from place of employment (hey - I made that one up).
