Romans 12:18-21

Do your best to live in peace with everyone. My friends, do not try to punish others when they wrong you, but wait for God to punish them with his anger. It is written: “I will punish those who do wrong; I will repay them,” says the Lord. But you should do this: “If your enemy is hungry, feed him; if he is thirsty, give him a drink. Doing this will be like pouring burning coals on his head.” Do not let evil defeat you, but defeat evil by doing good.
