The only people with whom you should try to get even are those who have helped you. (John H. Southard)
Getting even seems to be an innate reaction when we’ve been mistreated or hurt in some way. Of course, we don’t try to just get even; most often we want to get back at the offender with a greater hurt or pain. How much better life would be—and our spirit helped—if we would try to help those who have helped us and try to forget our personal hurts.
Do not take revenge . . . for it is written: “It is mine to avenge; I will repay,” says the Lord. On the contrary: “If your enemy is hungry, feed him; if he is thirsty, give him something to drink. . . Do not be overcome by evil, but overcome evil with good. (Romans 12:19-21)
