I'd like to offer my experience with what "it" is that JamesThomas and poppers, and now purps, and many others on JWD are finding.
Not that anyone will care. But, in response to the comments of Narkissos, whom I respect as being very well-read and intelligent, I feel an urge to give my two cents.
When I was an active Witness, I fervently prayed to Jehovah to help me to see what was real. That's all I wanted. I didn't have to like it or dislike it. I just wanted to live in reality. Strip away all the illusion. At the time I prayed this, I was unsure of the very existence of Jehovah. Still am. In fact, I'm pretty certain that He, as we have learned Him to be, does not exist. However, once I made that my desire, to see reality, with clarity, that is exactly what began to happen. Mental clarity. All my questions answered? Of course not. But, I'm no longer identifying myself as one of Jehovah's Witnesses. And that feels right. I always knew something was wrong there. I just wasn't ready to accept it.
When I started posting on JWD, less than five months ago, I started to identify the various camps. Christians of different persuasions, some claiming to have had spiritual experiences with Jesus Christ, even being called to various ministries. Others were very well-versed in the Bible, from a scholarly standpoint, but hesitated to share where their studies had left them with regards to personal belief. Then the agnostics. Then the atheists. Then all kinds who resist labels of any sort. I'm sure I'm leaving out a bunch.
Was I looking to fill the "void" left after abandoning my life as a Witness? Perhaps. I'd rather call it a keen desire to gain further clarity about all that is life and the universe of which that life is a part. When I read JT's posts for the first time, I felt he was on to something. Then I noticed poppers expressing similar ideas. I still don't know what to call "it". No one has asked me to send them any money. No one has asked me to go join a group. No one has told me that if I don't believe this way or that way, I will suffer disastrous consequences. I simply was invited to observe what's been there all along. I was already becoming "aware". Now I just found myself, for the first time in my life, in the company of like-minded individuals. If I am on a dangerous path, or otherwise in error, I invite sincere advice.
I've come to no final conclusion about anything. I cannot go back to being a Witness, not knowing what I know. I welcome any observations. If I'm missing something, if someone knows of something better than quietly contemplating what remains after all the dogma and prejudice and assumptions and self-imposed limitations of attention are stripped away, I'd love to hear about it. Sincerely I would.
