An excerpt from "Got Questions.org" entitled, "What does it mean to love your neighbor as you love yourself?" states: "Notice that loving our neighbor would include sharing with the poor and the alien; compassion and absolute honesty and justice in our relationships with others; impartiality; a refusal to be a party to gossip or slander; an absence of malice toward anyone and a refusal to bear a grudge; taking care never to put another’s life at risk and never taking private vengeance upon another. It is also interesting to note that when we have an issue with anyone, we should strive to make it right by going to him or her directly. James calls this the “royal law” (James 2:8). Our Lord taught that we should do to others as we would have them do to us (Matthew 7:12)."
