Buffy you have every right to not want anything to do with religion. That was your freedom to choose. Not to mention you have not been out that long. Finding a faith/re-programming yourself doesn't have to be something you take up within a certain time peroid. If you are happy not being in a religion don't be in one. I would guess your doubts are still the residue of JW guilt that you have to attend church/meetings, what have you, in order to be a spiritual person. That's a load of hooey of course.
If you are worried about your son, you are much better off letting him make his own choices about spirituality then to sign up for the nearest church with the best slogans.
My advice, for you and your son: take a cosmopolitan attitude. Start reading some stuff. See what makes sense to you and is inline with your own understanding of God and spirituality. This will help you a lot, to make up your mind if you want to be in any religion again ever, or if you would rather be a spectator than a participant when it comes to religion. Plus it will teach your son tolerance. Instead of getting him hooked up with a doctrine that teaches "we are right, they are wrong" (which is what every religion teaches by the way) he will be able to develop some critical thinking skills. Granted I have no idea how old your son is, or how ready he is for that, but I would have an open church policy. If you guys want to go to a buddist temple go. If you want to go to a mosque why not check it out. Baptist/Luthern/Catholic...whatever. IF ya like what you see, you can always go back.
People spend more time shopping around for a VCR than they do religion.
I myself am doing a little checking out and reading for myself. So far lots of interesting information, but nothing that made me feel like I had to join. That might change, that might not. In the meantime I am keeping my options open.
