Love God, Love your neighbor !
Who is my neighbor you might ask?
Someone asked Jesus the same question.
He answered by telling them a story of a man, despised by the accepted culture, who stopped to help a total stranger, from the accepted culture, who had been beat up and left for dead. No one from the accepted culture stopped to help the culturally accepted man, but the culturally unexcepted man stopped to help a wounded man that might hate him.
In other words: Your neighbor is any one whom you come in contact with or with whom your actions may effect, even those that hate you.
