According to Rom 12, we are to be transformed by the renewing of our minds. Paul likens us each to one body part which should be a part of a larger body. He calls us to be sincere, cling to what is good, be devoted to each other in love, honor each other, be zealous for God, be joyful in hope, patient in affliction, faithful in prayer, share with the needy, provide hospitality, bless those who persecute us, and have empathy on those around us. Live harmoniously and do not be too proud to associate with those in a lower status. Do what is right in the eyes of all and live at peace with everyone - so long as it depends on you; the LORD will repay
If your enemy is hungry, feed him; if he is thirsty, give him something to drink. In doing this, you will heap burning coals on his head
