If JWs did the following, I believe they would grow exponentially and become one of the largest 'religions' on Earth :
1. No more DFing or shunning......its up to your conscience who you like or don't like. in the same way if i was Catholic living in Ireland, I wouldn't hang out with my neighbor if she was a drunk fornicator, just had an abortion, had a Taliban boyfriend and also supported Liverpool Soccer club. Specifically the latter.
2. No more 'ministry' going house to house or street witnessing.
3. Spend 10-130 hours every month helping fellow human beings practically, emotionally and financially who are NOT JWs or family members. And optionally fill an S8 every month re above.
Universal Unitarians on steroids? 50% of the current JW cong would be auxiliary pioneers half the year. What do you think?
