The funny thing about the "Spiritually weak" label is that those people were often in my experience the ones who were , looking back, partially awake, and so had stopped faking it.
The ones judged to be "spiritually strong" were usually faking it, we had Elders, Pioneers and "strong" Publishers who I know were faking ministry time, so what kind of moral standard did those people have ? did they really believe in Jehovah ? surely if they did they would have been afraid to lie about what they did in " his service" ?
I'll admit there was the odd, zealous, 100% believer, but they were rare as Rocking Horse Poo, so the ones we were supposed to associate with were Fakers, Liars and Cheats.
No wonder I was always found among those considered " Bad Company".
