The world in which one person lives is too limited and restricted. When rubbing shoulders with another, we gain a panoramic view, which allows us to see the whole picture. "As in water face reflects face, so the heart of man reflects man" (Proverbs 27:19). That's so picturesque! People provide a clear reflection of what is in the heart. A mirror goes only skin deep. The counsel of a friend reflects what is down inside.
