Interesting points. I've been thinking back on what it was that drew me to the JWs, and I must admit part of it was the clean lifestyle promoted. Another part was sincerely wanting to do the will of God. However, I can see that they do not do the will according to knowledge, and over-inflate the preaching aspect. I've long thought they went on more about the preaching than even the Bible did.
Yes, I've drawn much praise over the years as a clean living, respectable, decent person. And that's a good thing. Being determined to what's 'right' kept me out of trouble I believe, though it's a pity about all the other rubbish I had to swallow along with the clean living and being nice thing. I curbed my anger management issue I had when I was a teen, and now I'm as cool as a cucumber. I put a lot down to maturity, and a lot down to actual Bible verses I've applied
Although I never made a convert, like most of us, I acted the role most of the time though when it came to field service and that. The only thing I liked about witnessing was hanging out with friends and seeing cool houses.
