It's a terrible thing to actually lose one's faith. We humans can't really live without faith, as we simply don't have the knowledge to tell us how to make realistic decisions. All of life is an act of faith, for us, as we don't really have anything else to go on. To lose that faith is to lose the ability to make any decisions at all - to even decide to keep living.
We can, however, change the paradigms (conceptual constructs of reality and truth) that we are placing our faith in as we live our lives, and many of us do. This is not easy, and is often a frighteneing experience for us, but we can do it. And this is really what "Granite1010" is talking about, I think. He hasn't really lost his faith at all, he's simple rethinking and re-evaluating the paradigm that he had traditionally been putting his faith in. I think this is good and healthy for any of us to do, even if it is a bit frightening for us in most cases. I applaud anyone who has the courage to honestly re-evaluate their concepts of what is real and true. Many of us will be too frightened to do it, and will instead fight tooth and nail to protect the paradigms we currently hold no matter how irrational and antagonistic we become as a result. And in fact, this is why we're seeing all the insults aimed at "Granite 1010" and "Wickwoman" as they discuss the flaws in the religious Christian paradigm. Those insults are really just the defense mechanisms of people who are too frightened to honestly consider the possible flaws in their own beliefs.
