Either some invisible scientifically undetectable conscious entities exist or they do not--that is, they are all as imaginary as Zeus or fairies. There is no scientifically valid reason for believing in the former... yet believers do believe in the former... and they believe in particular versions which automatically exclude other versions. Not only do they believe in the former, they assign characteristics to their imaginary friends and claim to have access to some divine truths. That's just ridiculous. They don't believe each other's truth, because each has a truth invented in their own mind... god can be whatever makes you feel good or whatever you want to believe. You presume that you know some "truth" while you have rejected that means of knowledge for another. You reject Scientology and astrology for skeptical reasons... but you don't apply those skeptical reasons to your god. You cannot admit that the god you believe in might be as much of an illusion as Scientology's Xenu...
Keep trying to convince yourself... or the troll on this thread

You can't convince anyone rational that you are making any more sense than that doublespeaker... whom you may or may not agree with. But you come off similarly smarmy.
ETA: Christian Skeptic... I have re-read you. I guess I had thought you were saying that you looked at the situation skeptically and you've concluded that Christianity is true, and now you want to hone that truth. I guess you weren't saying that. Yes, there are ex-believers of all religions. I thought you were making the equivalent of this argument Tom Cruise could make, "ever since I've been using the principals of Scientology, my life has gotten better and more prosperous... that is proof to me that it works... that it's true... I will use my tools of skepticism to hone that truth and come to a clearer understanding of the truest truth of Scientology teachings I can find."
As you can see, that sets someone up for confirmation bias. If a visitor comes to your town at the same time as a natural disaster and you kill that visitor believing he brought the disaster... then the longer that disaster doesn't occur, the more you will think it's because you made the right decisions and that the disaster really was brought by that stranger. If the disaster does reoccur, you might look for the next person that needs killing. Once you have a belief based on a giant leap... your brain confabulates the truth is support of that belief... your brain is always trying to make sense of the world. Once Tom Cruise confabulates reasons as to how he knows Scientology is the truth, he will notice all evidence that confirms that belief and negate all other evidence.
Fundamentalist Christians are told that people will test their faith... so when they doubt, they think it's a "prophesy" fulfilled. Mormons are told to pray to know if the Book of Mormon is true and God will tell them... but that begs the question that there is a god and it's manipulative, because they are looking for signs and are likely to find them... and lots of Mormons get that sign... it doesn't make the belief true. I would like to think that some belief somewhere was more than this... but, like Randi, and many people here... I have just seen how easy it is too fool people... how people will grasp at stupid explanations rather than say they "don't know"... how some people cannot stand to think that they can be fooled in the same way that those they judge as foolish have been fooled.
I would like to believe that someone somewhere really believes something because it has a basis in some kind of fact or useful knowledge... but that just doesn't seem true. They all sound the same as my examples... as you. When something is true, like evolution, the data amasses like the decoding of genomes... when something isn't true, it's just semantics, and anecdotes, and tangential questions like Bigfoot believers and conspiracy theorists and crystal healing. Truth snowballs... scientists love amassing more knowledge and using that knowledge, but delusions just snowball in words and bs and nothingness and doublespeak.
I don't believe that objective truths can come through faith or feelings. I see no evidence that this is the case and lots of evidence that this is a major way people delude themselves.
