Peter tells us as does Paul not to return evil for evil noir reviling for reviling (1Peter 3:9; Romans 12:16,21). Peter instructs us to rather bless the person who wants to do us evil. Paul says we are to do them good.
Our sinful nature bulks against these instruction. We say, Why should I bless him or do good for him when he purposely hurt me? That does not make since.
But our sinful nature has been brought under control by the Holy Spirit because he has imparted to us the divine nature. (2 Peter 1:3). Jesus suffered for us while we were his enemies that he might bring us to life. Our kindness to those who wish to harm us, gives them the opportunity to repent.
