I strongly suspect that a whole lot of the good religious folks do flies well under the radar of public notice, perhaps for two main reasons.
First, it is too trivial, too commonplace, to be 'newsworthy'. When a pastor or church member visits a sick person to console them, or when a church donates money to another church's soup kitchen, or when some other such commonplace thing is done, it is never reported far and wide. Never. Hence, I would wager none of us have a clue as to the scale on which such actions take place every day across the whole country.
Second, a whole lot of good deeds are assumed to have nothing to do with the doer's religiosity when, in fact, the doer themselves is indeed motivated in whole or part by their religion. Case in point. Years ago, I and a friend built decks for people. One of the decks we built was for a man who led an adult discussion group at his church. He would more or less daily check up on us to make sure we had such luxuries as lemonade, the right tools (he had a vast collection of tools he was willing to share), and so forth. In other words, he was very solicitous of our welfare. I thought nothing of it until one day he got to talking about how two or three years ago, he had 'soul-searched' himself and found himself wanting in his thoughtfulness (or lack of it) for other people's needs and concerns. He had then consulted his Bible and decided he would try to emulate Jesus a bit in becoming more mindful of other people. Yet, had he not mentioned all that to my friend and me, I would never have suspected that all his acts of kindness were originally inspired by his religion.
