I have been through many stages. I have been ultra-religious - to the point that I was going to be a missionary in Africa. I attended Church, Bible study, part of the youth leadership, in the church band.... etc. I was even baptised in the holy spirit. Then something happened that made me look at the Christians I was surrounded by. I was horrified at the duality of human nature (I am still naive when it comes to many things). I began to ask questions of the religious leaders - and they were not able to answer them to my satisfaction.
For many years I was nothing - and happy to be that. That is when I met my husband. He considers himself Christian (though not practising) - I am a bit more pragmatic. I got to a point where the esoterical started to interest me. I investigated Paganism, Wicca, Hinduism, and many others. The only thing that rang true for me, was that we are all connected. We are all energy. I called myself agnostic for a while - but knew it wasn't true. But it was easier to say that than what I mentioned above
I even looked into the Church of Satan - and found out it was nothing that I expected. Many of their tenants feel right. Do what you want - as long as you harm none. This is very different from the popularised Satanism.
I don't believe in a god - but a consciousness of which we are all a part. Yes - madness I know - but I have no trouble with that idea.
