Romans 12:17-19

17If someone has done bad things against you, do not do bad things back to them. Try to live in a good way so that people will respect you. They will see that you do good things.

18If it is possible, try always to be friends with other people.

19My friends, if someone has done bad things to you, do not try to punish them yourselves. Instead, let God be angry and punish them. This is what is written in the Bible: ‘The Lord God says, “When people do something wrong, I am the one who will punish them. I will pay them back.” ’
