OK, I am currently doing a bible study, with a man I class as a great friend.
He listens to some metal, and so do I-the elders of my Kingdom hall are aware of this. I am not yet baptized, but have been going to every sunday meeting for around 7 months (I have missed last weeks and this weeks due to being Ill, and my friends mum is currently undergoing chemotherapy, so infection is really not good, so I need to be fully well before I am back studying and attending meetings).
I have started to go to Thursday meetings to, which are more to do with field service and witnessing, and thoroughly enjoy it.
Now, I don't know if it is different here in the UK-but I have been told by the elders, metal and the like IS advised against, but it is how it personally affects YOU that it the issue. If it makes you happy, and is not blatantly evil, like black metal, there is no issue-however, if it plays on your mind a lot and makes you depressed, then it is bad.
I have learnt so much in my study, and I was looking for a faith for a long time, I always thought JW's were strange people who occasionally knocked at your door to preach-but I always spoke to them.
Eventually, the person I am doing my study with knocked with another very nice gentleman, and that is when I said "why not, I am interested".
I found my ideas around JW's were completely different to what we actually believe-and to my astonishment, it was what I already believed, I just did not know this!
I live in the UK, so I don't know if that is why there is a difference-but I know there should not be, as worldwide we read the same watchtower, study the same thing, where as other "Christian" churches teach whatever they want, and keep you going by fear of hell. I was glad to learn hell did not exist-and that I had never done anything in my life bad enough to not warrant resurrection/survival of the end.
So, it seems odd with the music, but as long as in your heart you are a good person, and are following what you should be, me and the elders at my local hall see no issue with music, even metal. Like I said, it is how it affects you personally.
It is quite daft some of the comments I have read, that people have been approached by their elders after someone else has seen them driving playing the "wrong" type of music.
I also vape-I do not use nicotine anymore, and the Elders and other witnesses think they are great, and see no issue with that either-I make my own juice, and am not putting anything inherently dangerous into my body, so they have no issue there either.
All the best, Conan.
