This has nothing to do with anything. You call it "empiricism" because you can't call it faith. And it's just silly because everyone else calls it faith, and knows that's what it is. That that's the term that best describes it. Through the imagined remediation of some 'magical' entity, one is able to do for themselves what they were not otherwise have been able to do. It's as simple as that. You can whine and complain that the entity is not real, but honestly, no one cares. The possibility of God S REAL, and the results of trusting in that possibility ARE REAL. The healing is real. Lives are changed, and usually for the better.
There is nothing stopping an alcoholic from refusing to take the next drink. But millions of humans beings are going to die this year because they could not figure out how to just say no to that next drink. You presume that logic must always be effective, when clearly, with we humans, it rarely is. We NEED other methods. And for a huge number of us, faith is that more effective method.
Well, the evidence clearly shows that you are wrong.
