Romans 12: 17-21 = Never pay back evil with more evil. Do things in such a way that everyone can see you are honorable. Do all that you can to live at peace with everyone. Dear friends, never take revenge. Leave that to the righteous anger of God. For the Scriptures say, “Vengeance is mine; I will repay,” says the Lord. Instead, “If your enemies are hungry, feed them. If they are thirsty, give them something to drink. In doing this, you will heap burning coals of shame on their heads.” Don’t let evil conquer you, but conquer evil by doing good.
By giving an enemy a drink, we’re not excusing his misdeeds. We’re recognizing him, forgiving him, and loving him in spite of his sins, just as Christ did for us.
Matthew 18: 21-22 = Then Peter came to Him and asked, “Lord, How often should I forgive someone who sins against me? Seven times?” “No, not seven times,” Jesus replied, “but seventy times seven!”
