LHS, believe me, most if not all, of us are NOT from satan. I can honestly tell you that since leaving the witnesses (and I did it slowly) and joining another church, I am a better, less selfish, more spiritual person. You sound very similar to me, with similar doubts. I used to read the context of scriptures too and saw how they twisted them to suit their own means. To me, the scriptures were much more beautiful IN their contexts! And their meanings were much more simple, and surprise, a whole lot more like 'christendom'.
Tell me, is your husband a witness and if so, what is he like? Is this the same husband you suffered abuse from, or is this your second marriage? If I was you I would definitely celebrate your sons 16 th birthday!! it sounds like your 14 year old may have already gotten baptized? She can still fade out too in either case. Try to encourage her to do things with friends from school, join a club etc. really, that is the most important thing for her right now.
Your life is about to get better! I am hoping your husband makes this easy for you by agreeing with you. Let us know. That will make a big difference. I managed to bring my whole immediate family with me and they are all happy to be out of it, and one of my children was 14 at the time and resistant to change. Then, she made a lot of friends at school and has a boyfriend and is so so glad to be out.
Holidays don't bother me at all, it's just witness extremism. Research doctrinal issues from websites. Just type in doctrines and see what comes up. Get your purple interlinear out. Get another Bible too. I believe in evolution as well, as part of the creative process. Fundamentalism is not important, many parts of the Bible are from a human perspective and for an ancient mindset. Jesus explains who God really is, he is the exact image of him.
There is definitely life after the witnesses! You will not miss anything about them, except family who are still in. See what you can do to start living now! But save money for retirement!
