A son has faith in his father not because he has evidence that he will fulfill his future promises, but because he has evidence that he has fulfilled his past promises.
Faith means educating your view of things which may not be seen based on evidence. Proof requires no faith. Evidentiary claims do.
Belief: I believe that road will take me to New York. That means I believe that road goes to the direction of New York. I believe that if I were to take that road, it would take me directly to New York.Faith: I have faith despite everything that can go wrong during the trip like being in a car crash or the car breaking down, that there is something blocking the road. I have faith that it would have been worth it in the end. That if things turn out badly, I was in the right to take the trip anyway.That is why I said faith is impractical. By having faith, you automatically let enter some doubt. There is no blind faith. The opposite of doubt is not faith. The opposite of doubt is certainty. I also said faith is not of this world because faith automatically introduces alternative worlds where what you believe can be wrong. Faith is different than belief because you are participating in faith actively and risking.A driverless car doesn't car about alternatives even though it may be programmed to consider alternatives. A driverless car doesn't car about reaching New York. It is simply programmed to. And a driverless car doesn't care about failure. It is not programmed to care. That is why I said faith is impractical. But faith does make us human. And it is out of this world since humans see what a driverless car can not.
