Stopping attending meetings signifies;
- no longer "loving Jehovah"
- turning one's back on Jehovah
- tacit admission of wrongdoing
When I stopped attending the meetings, and told an elder (James Bovill) such, his reply included "you've turned your back on Jehovah", "Jehovah gives us two choices, life or death, it's clear which choice you've made", and "well, if there's wrongdoing involved it's best not to discuss it with others" (there was no wrongdoing involved).
Christians are supposed to believe that salvation comes through going to the Christ. Jehovah's Witnesses believe it comes from going to the meetings.
