David Brazzeal said this quote
“ Although I had nothing to offer in return, I came to understand that there was something beneficially reciprocal happening to the people who were blessing me. For a few minutes, they suspended their normal egocentric lives, placed a fellow human being in higher priority than themselves, and expressed their hopes for the other's peace and well-being. In so doing, they inevitably lived life on a higher plane, if only for a few moments. It always smelled like the kingdom of God to me. ”
