When others wish us harm, God instructs us to react with love, not with evil.

A soft answer turns away wrath, but a harsh word stirs up anger. (Proverbs 15:1)

Blessed are you when they revile and persecute you, and say all kinds of evil against you falsely for My sake. (Matthew 5:11)

But I say to you, love your enemies, bless those who curse you, do good to those who hate you, and pray for those who spitefully use you and persecute you. (Matthew 5:44)

But, love your enemies, do good, and lend, hoping for nothing in return; and your reward will be great, and you will be sons of the Most High. For He is kind to the unthankful and evil. (Luke 6:35)
