The fact is, however, that “mankind” or “the people” does not exist as a person for whom you could do something right now. It consists of individual persons. By doing something for one person, we are doing it within the general mass of humanity.
If each one of us did what was possible to do for whoever was standing right in front of our eyes, instead of goggling at the community of mankind, then all people, in aggregate, would at each moment be doing that which is needed by those in need, and by satisfying their needs, would establish the welfare of all mankind, which is made up of haves and have-nots, the weak and the strong. But those who keep thoughts of the welfare of all mankind inattentively let slip by that which is in front of their eyes. Because they do not have the opportunity to perform a general work, and let slip by the opportunity to perform a particular work, they accomplish nothing towards the main purpose of life.
—St. Theophan the Recluse, The Spiritual Life
