Snorbs - I think you've hit it with prayer - its a behaviour which has evolved because it does something for the pray-er. Gives them an illusion of control maybe. Meditative (as opposed to intercessory) prayer might have some deeper mental effect akin to Buddhist meditation maybe (which of course is entirely non-theistic).
Its another example of how religions are rationally explicable.
Mos: > I don't think God cares one bit about whether a person follows one religion, or another, or none, and certainly not about people's sexuality.
If this was the case, why would these beliefs be so prevalent, a major feature of many religions? If there was a God, surely he could reveal himself a bit better so that his followers, in their different varieties, didn't spend so much of their energy on judging other people's sexuality and warring (metaphorically and literally) with people who have a different religion.
The 'all religions lead to god' idea is intellectually dishonest - they are just too incompatible. If you're a Christian, surely it matters whether Jesus was actually the Son of God, resurrected versus the Muslim's mortal prophet (or the Hindu's position of irrelevance, come to that). These positions cannot all be true.
As soon as you start to think about this, surely you either have to pick one or throw out the whole lot. That still leaves you able to believe in some sort of god if you 'feel a presence' - but that's about it.
