When I was one of Jehovah's Witnesses I was absolutely sure I had the truth. So sure I would have been willing to sacrifice anything for my beliefs. I worked hard at study, meetings, service - even aux. pioneered while working full time.
Now - many years later I know that I was fully deceived.
I became a born again Christian a few years back. I have spent my fair share of time studying the scriptures and researching history of JW's as well as christianity and other religions. I believe in God and I believe that Jesus was his son. I am much happier now. But I have to be honest with myself and admit that I am "deceivable". I was deceived once - it would be much harder to deceive me again - yet - it COULD happen.
So what about you. Regardless of your belief system now - do you admit that you can be deceived?
