Peer pressure. I have 30 years invested. Friends, family and the like are mainly Witnesses. After the generation change, I began to fade, I read COC and "My eyes were opened". I do not feel the obligation to EARN salvation anymore. Although still associated, I have non-witness friends, my children play sports and Karate. I am free. I do not attend meeting regularly but notice the guilt that others feel when they can't attend service or miss a meeting. Their families are neglected.
A teenager told my son that our family was spiritually weak because I miss meetings. My 15 YO bluntly told him how our family was normal. He mentioned how his mother was addicted to anti-depressants, like most women in the hall. My said spoke of how I, his dad spent many hours with the family every week. Other than FS the other child said he never spent any time with his father. After a 20 minute debate, during the TS, the child asked his dad to step down and spend more time with the family.
Many witnesses are drones. The end of the world is coming so there is no time for carrer jobs, just field service.
