We tend to condemn in the system what we do not recognize in ourselves. Sins do not exist in general; they are specific, concrete, carrying their weight measured in terms of fearful accuracy. We do not sin against humanity; we sin against persons who have names, who are actual, breathing, human beings. The root of what I condemn in society is found at long last in the soil of my own backyard. What I seek to eradicate in society that it may become whole and clean and righteous, I must first attack in my own heart and life.
