Honestly,
I have met more spiritual people OUTSIDE of the JWs than inside of it.
I've met, in the 8 years since leaving, people whose bible knowledge puts the JWs to shame. I'm not kidding. There are people out there who know so much more about the bible than JWs do. Some of them accept Jehovah as Gods name and they preach to others (but not door to door usually).
I've also met really spiritual non-Christians. People whose lives are truly about giving to others. They spend time each week giving to others and doing things for others. There are people like that on this board, but of course they don't advertise it because they are not like JWs (they don't need to prove themselves to everyone else, theirs is a relationship between them and god). Some spend hours and hours doing healing and prayer for those who are ill. Some give up their time to do charity work or community projects.
These are the people you need to be around. These are the people you need to copy if you want any fulfillment in life.
I'm only just learning this myself but I will tell you for certain that the JWs are a spiritual wasteland. It is really ridiculous to imagine that God, in 1919, did an inspection of religions and chose the bible students! Its even more ridiculous to suggest that he continues to approve of them - the religion with a sordid history of false prophyseys, destroyed lives and families, abused children and a trail of blood behind them which is always covered up! They don't even follow their own rules and beg for forgiveness for the millions of people they have hurt.
You just need to make the effort to find people out there who are truly spiritual. You might not find them in the first Christian church you visit, either.
