Small, routine, good deeds of ordinary folk going about their daily lives—that is the great power that stays back evil and injustice. Like drops in a rain storm washing away the drought, no single part seems too significant in itself, but things so small can’t possibly operate alone. No rain drop is ever alone because rain only falls in large numbers from a looming cloud.
Evil and injustice only have chance to spread when people believe that they don’t matter merely because they are small. Small things always come in numbers, so they always matter for better or worse.
