Jesus is Lord - Romans 10: 9
1 Thessalonians 5:15
15Make sure that nobody pays back wrong for wrong, but always try to be kind to each other and to everyone else.
Romans 12:17-19
17Do not repay anyone evil for evil. Be careful to do what is right in the eyes of everybody. 18If it is possible, as far as it depends on you, live at peace with everyone. 19Do not take revenge, my friends, but leave room for God's wrath, for it is written: "It is mine to avenge; I will repay," says the Lord.
