Romans 12:14-17

Wish good for those who harm you; wish them well and do not curse them. Be happy with those who are happy, and be sad with those who are sad. Live in peace with each other. Do not be proud, but make friends with those who seem unimportant. Do not think how smart you are. If someone does wrong to you, do not pay him back by doing wrong to him. Try to do what everyone thinks is right.
