Some of the examples you give are hard for me to relate to because in my faith, there is no point in doing things just to “prove” faith. The best proof of faith is to live with integrity and fully by my beliefs. And I have done a whole lot towards that end, but most of the things are purposeful. Now, those people may find what they are doing purposeful as well, but those types of things are not seen as necessarily purposeful in themselves in my faith.
I have spoken up when I observed injustice, left jobs because people did not behave honestly and forthwrightly, lived in poverty, made a variety of sacrafices of time, energy, money, comfort, etc, because of my faith, but I do these things because I believe my faith is the truth, and the best way to live. I don’t do them to “prove” anything to anyone, natural or supernatural.
