Repay Good for Evil
Rom 12:19-21 Do not take revenge, my friends, but leave room for God’s wrath, for it is written: "It is mine to avenge; I will repay," says the Lord. (Deut 32:35) On the contrary: "If your enemy is hungry, feed him; if he is thirsty, give him something to drink. In doing this, you will heap burning coals on his head." (Prov 25:21,22) Do not be overcome by evil, but overcome evil with good.
That is you bring shame to your enemies by returning good for evil. The burn coals are the convictions of sin which burn the heart, leading to humiliation but which may bring a person to Christ. Peter writes, "Who is going to harm you if you are eager to do good? But even if you should suffer for what is right, you are blessed. "Do not fear what they fear; do not be frightened." But in your hearts set apart Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect, keeping a clear conscience, so that those who speak maliciously against your good behavior in Christ may be ashamed of their slander." 1Peter 3:13-16
Likewise Jesus said, "Do not resist an evil person. If someone strikes you on the right cheek, turn to him the other also. And if someone wants to sue you and take your tunic, let him have your cloak as well. If someone forces you to go one mile, go with him two miles. Give to the one who asks you, and do not turn away from the one who wants to borrow from you. "You have heard that it was said, ‘Love your neighbor and hate your enemy.’ But I tell you: Love your enemies and pray for those who persecute you, that you may be sons of your Father in heaven. He causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous." Mt 5:39-45
