Versions of the so-called golden rule are found in most major world religions. For example, Confucius says, "What you do not want done to yourself, do not do unto others." But Jesus stated an old truth in a new and positive way. "Do unto others as you would have them do unto you" (Luke 6:31).
The ethics of reciprocity also appeared in the Beatitudes when Jesus said, "Blessed are the merciful, for they shall receive mercy," and elsewhere when he said, "Give and it shall be given to you" (Luke 6:38).
What's so golden about the golden rule? You can analyze it all day long. But you'll know only when you put it into practice.
