IHi Andromeda, ( interesting name, considering the ancients, including the Jews, were and still are very obsessed with the movements of the heavenly bodies). I think if you feel that the sabbath should be kept, and it makes you feel better to observe it, do. It is [i] your[/i] life and no one has the right to control your beliefs, actions and thoughts. I personally believe Jesus' message around the sabbath, as around everything, is that love comes first. Want to observe the sabbath? Fine... But if your sick friend requires you to help her with chores.., go ahead, love is the priority.
I believe you would benefit from a book by an author called Steve Hassan called Combatting Cult Mind Control. You've nothing to loose by reading it and everything to gain. It is not against religion by the way.
please take care, there are many splinter groups that left the WT despite what they say, they themselves being an offshoot of Adventist and Millerism etc. you may find you have more in comman with them.All their predictions have not come true, Jeruselem didn't fall in 607BC therefore the GB do not have the Holy Spirit more or less than anyone else. Do keep researching.
