I don't have zero evidence aside from an old book. I've seen and felt things that give me evidence that it's true. The problem with me saying that to anyone who doesn't believe, is they'll just think I'm crazy. There's as much solid evidence for me to believe in Christianity as science can get to explain the world. I've seen examples in the real world that play out with the hypothesis that Christianity is true. It's already been discussed here, that everything in the scientific field is limited by our perceptions of the world and our perceptions of the results of scientific testing. Also Christianity explains things science cannot, IMHO.
That's just the delusion. I've seen unicorns on a mountain far far away, but nobody is going to believe that story. How does this sound to you? I've also experienced and seen things while meditating that I can't even properly describe.
Should I tell everyone that "god" has contacted me and that I'm going to be your next savior? Just because you feel or see something that you can't describe you can't say that it is "god" since you don't know.
Things happen in the name of Jesus Christ that wouldn't if you didn't call upon him and His power. I believe that and have seen it, others believe that too. That is what makes it God versus something else. I know anything I say that's happened from calling upon Him, you will still argue it was something else, maybe a self fulfilling prophecy. I'm not going to argue that with you.
When people see things that cannot be explained and miracles, they can either be explained away by science, or it's proof of something else going on that science has not explained (which means a religion may be right). I never really believed this: but atheists do seem to put a lot of
faith in science, to the point it
seems like a religion, since science has not explained everything, and continues to learn, and has changed the way we perceive things from the past scientific explanations. (

I don't argue science can't be helpful, but to believe
only what you've seen, it cannot give you the whole picture. That's why there's so many theories in science, and why things change when people get better at looking at the evidence. Like what's the smallest thing in the universe? (
