Believe it or not, I was actually once religious, around the time of my confirmation and a few years after that. But slowly doubt crept in and my views have changed. While I might be open to a vague notion of a deity (and I don't believe in that either), it certainly has nothing to do with any that the organized religions promote. I am still a member of the church for some personal reasons, though I plan to separate from it later on in my life.
But I think saying that "nothing will happen without an open mind" is a bit disrespectful towards some people (or perhaps I'm misinterpreting). I'm willing to bet there are hundreds that have really struggled and tried to find their faith but have "failed" and are now atheists. I've heard many such things in the US for example, where faith is such a big deal. Losing their faith there has been a tremendous process and involved a LOT of Bible studies etc. Are you saying that they have not approached the subject with an open mind?
That is a very good question. I will try to answer it tomorrow if you don't mind - been up for 30 hours straight as of now.
