“The second is this: ‘Love your neighbor as yourself’” (Mark 12:31).
Second only to the responsibility to love God with all you are is the command to love your neighbor. However, again, “love” is a weasel word in our society. So what does it mean to love someone? Jesus helped us out with some statements that will make it clearer.
“So in everything, do to others what you would have them do to you, for this sums up the Law and the Prophets” (Matt 7:12).
We’ve labeled this the Golden Rule. It’s simple: Knowing nothing about that person, if you were the one in that situation, what would you want people to do for you? Many societies have a version of this, but it’s typically the negative, eg, “That which is hateful to you, do not do to another.” The negative is easy: If you don’t want to be set on fire, don’t set people on fire.
The positive requires you to do for burning people what you would want someone to do for you — namely, extinguish the flames. The positive is less easy. When you see someone who is hurting, someone who is hungry, someone who is cold, you are to give what you would like to receive were you in their place.
The apostles take this command seriously.
