Therefore, whatever you want men to do to you, do also to them, for this is the Law and the Prophets.
Galatians 5:13-14 The Golden Rule is found, in varying forms, in all religious and cultural traditions, many predating the time of Christ. Ethicists call it the “rule of reciprocity”—letting how we desire others to act toward us be the guide for how we act toward them. But when Jesus Christ stated His version of the Golden Rule, He gave it a twist that had been missing in other cultures.
Prior to Jesus, the rule of reciprocity had been stated in negative terms only. For instance, the Jewish book of Tobit said, “Do to no one what you yourself dislike.” In other words, prior to Jesus, the Golden Rule focused on what not to do to others. But when Jesus stated it, He put it in positive terms: “Whatever you want men to do to you, do also to them.” Instead of only withholding negative actions, Jesus said to demonstrate positive actions: Be proactive in your behavior toward others by loving them the same way you would want to be loved. He said such a proactive posture was a good way to summarize the whole Old Testament: “the Law and the Prophets.”
Not doing bad things is commendable, but doing good things is even better. Doing both is to love as God loves.
Our job is to love people we don’t have to love.
