Religion and spirituality are completely different though. I don't care much for organized religion. The scriptures used tend to be full of wisdom; however, religion tends to build walls and create barriers between people. The idea that my belief system is THE right one and anyone who believes differently is wrong and needs to believe what I believe has not been good for humanity. My biggest criticism with religion is that it often creates people who want to force their beliefs on others and it creates hypocrites who do not practice what they preach without acknowledging and admitting their own struggles with following whatever it is they are preaching.
Where many people differ, I believe, on the subject of God is what/who/where/when/why he is. I myself don't believe that God is some guy in the sky running the show, but I do believe there is a God. I have many beliefs about what identifies God that I'm not going to go into. Part of my belief in God is definitely a result of my failure to see any purpose to humanity as a whole and by extension each individual life without a God. My belief in God has prevented me from seriously pursuing suicide though I have contemplated it many times. We know so very little about what we are capable of observing in the universe that I believe it will be a long time before we are even close to proving or disproving the existence of a higher power.
I most easily see God's existence in "coincidences". Often times I ask myself what is the purpose to some seemingly random atrocity, annoyance, accident, or even act of love. After enough time, I am generally able to see the purpose behind what happened or at least see how it could serve a purpose past what I can observe in the universe. These sort of events can easily be dismissed as mere coincidences but as they start to happen frequently viewing all of them as random events becomes scientifically absurd. I believe God can most easily work through anything that involves randomness or chance. According to quantum physics and the multiverse theory, I am in the universe corresponding to the events I have observed merely by chance and that there are perhaps an infinite (or at least incredibly large) number of copies of myself in which every other possible outcome of every possible event is experienced. This theory best fits the current mathematical models; however, mathematics itself is a bit of an abstraction. Also, the models we have now are based only on what we currently know and could be completely wrong no matter how complete and true they may seem. The idea of a spherical planet was once an absurdity as well as the idea that the universe does not physically revolve around our planet. Even the idea of aether (or quintessence) from Aristotelian physics that was dismissed has some truth to it.
I'm not sure what posts you are referring to. At least from what I have read on bluelight, it seems that those who are atheist or agnostic are more apt to express their beliefs, forcefully, on bluelight. I also think that the kind of religious people who would openly and forcefully express their beliefs have never heard of bluelight as these people are far from the drug culture.
And again as others have said, whatever helps you successfully overcome your problems and addictions without causing more problems than what it was worth definitely has legitimacy.
