It means repaying good for evil. Show kindness, love and treat them with respect. It may seem like “weakness” in the eyes of this evil world, but in spiritual reality, it’s strength. It makes evildoers aware of their own wickedness, and they hate it. It destroys their own delusions of “righteousness” and makes them feel ashamed.
Romans 12:19-21 “Dear friends, never take revenge. Leave that to the righteous anger of God. For the Scriptures say, “I will take revenge; I will pay them back,” 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.”
1 Peter 3:9–17
“Don’t repay evil for evil. Don’t retaliate with insults when people insult you. Instead, pay them back with a blessing. That is what God has called you to do, and he will grant you his blessing. For the Scriptures say, “If you want to enjoy life and see many happy days, keep your tongue from speaking evil and your lips from telling lies. Turn away from evil and do good. Search for peace, and work to maintain it. The eyes of the Lord watch over those who do right, and his ears are open to their prayers. But the Lord turns his face against those who do evil.”
“Now, who will want to harm you if you are eager to do good? But even if you suffer for doing what is right, God will reward you for it. So don’t worry or be afraid of their threats. Instead, you must worship Christ as Lord of your life. And if someone asks about your hope as a believer, always be ready to explain it. But do this in a gentle and respectful way. KEEP YOUR CONSCIENCE CLEAR. Then if people speak against you, they will be ashamed when they see what a good life you live because you belong to Christ. Remember, it is better to suffer for doing good, if that is what God wants, than to suffer for doing wrong!”
Hebrews 13:2 “Don’t forget to show hospitality to strangers, for some who have done this have entertained angels without realizing it!”
