I have been an atheist from about the age of 13. When I met my DH, who is / was* a practicing Catholic and from a very devout family (think 2 aunts who are nuns), I really wanted to be able to believe in order to have a bit more affinity with DH. I went to church, I closed my eyes for the prayers, did all the standing up and down, listened to the sermons. However, the bottom line for me is that I simply don't believe there is a god, much less, one who is remotely interested in the thoughts and actions of individuals, or who has power to influence events.
I have found Christopher Hitchen's work very good - although DH was a bit
when I asked him to buy the Portable Atheist for Christmas. I must say I find Richard Dawkins a little too strident and uncompromising for me.
It works well for us - DH is free to believe, I don't. It's not a big deal. We still celebrate Christmas & Easter, because for me, it is as much a family tradition than any religious celebration (and in the knowledge that they were both Pagan celebrations to begin with anyway
).
It might be worth reading around some of the critical thinkers on the topic, to give you more of an idea of what it is you think you are missing. I think it was Douglas Adams who said 'can't we just be allowed to enjoy the beauty and wonder of the garden without having to believe there are fairies at the bottom as well?'
*Since the whole child abuse scandal, I think it is a bit sad for my DH, because his faith in the Church has been badly dented. Having said that, I have always been extremely cynical about any organised religion - travelling round poverty stricken areas of South America which had the most ornate gold dripping churches sort of cemented my view on things.
