It is actions that beget belief. Belief without action is not belief. Imagine you and I were sitting in a café together, and I told you that I believe this café is currently on fire and will soon burn down, killing everyone in it. But I said it sitting calmly and sipping my coffee, seemingly unconcerned. You would look at me as if I were mad; clearly my actions are showing you I do not believe the building is on fire.
