What ThomasMore says is so true and doesn`t only apply to Jehovah`s Witnesses but also in many religions and cults .
My take on the matter goes something like this.
I`ve considered myself as a reasonably intelligent person and worked in chemical labs most of my life ,retired and bought my own home and live a comfortable life.
However I became a JW in my late teens being converted by a co-worker. I had always been curious about the Bible and what it was all about . My parents had made me and my sisters go to sunday school when we were younger and that`s where my curiosity started.
And JW`s seemed to fill that curiosity with satisfactory answers.And I was hooked for the next 32 years .
But their has to be a point where you give over your control of life to another person/ cause because you don`t have all the answers and you let some other identity make those decisions for you .And you don`t even realise what you have done.
Hence you become trapped in a cult .
