If your enemy is hungry, give him food to eat; if he is thirsty, give him water to drink.  In doing this, you will heap burning coals on his head, and the Lord will reward you. Proverbs 25:21‭-‬22

What is a sign of Christ in you?

One would be how you treat your enemies.  They hate your religion, maybe your color, sexual orientation or other things. They just do not like you and they show it.  This hate gives them energy to continue.  Defuse hate with kindness.

DO the unexpected

This verse says to do the unexpected.  To not reward evil with evil.  But show kindness by helping them in some outward way.  Take them to lunch! Help with gas.  Treat them with kindness. The Bible says this action will “heap burning coals on their head.”  In different version of the Bible it would call this “shame” or “unexpected kindness”.  The idea is not to use kindness as a way to cause them pain.  That would be mean. But maybe to offer peace. Maybe even receive a better understanding of your differences.

Elisha feeds enemies 2 Kings 6:8-23

The King of Aram sent an army to surround Elisha and kill him. In the morning Elisha’s servant looked out a saw the hundreds of soldiers surrounding them. Elisa asked GOD to open their eyes to see God’s army. Suddenly the armies of GOD were seen overwhelming the size of the enemy. Elisa asked God to blind this army.  Elisha could have taken advantage of the blindness and destroy his enemy. Instead, he had them fed and sent them back unharmed. They no longer harassed Israel.8-23

2 Kings 6:21-23 NIV

When the king of Israel saw them, he asked Elisha, “Shall I kill them, my father? Shall I kill them?” [22] “Do not kill them,” he answered. “Would you kill those you have captured with your own sword or bow? Set food and water before them so that they may eat and drink and then go back to their master.” [23] So he prepared a great feast for them, and after they had finished eating and drinking, he sent them away, and they returned to their master. So the bands from Aram stopped raiding Israel’s territory.

GOD will reward you.

Let your enemy respond however they desire for your kindness. GOD will reward you. You may put burning coals on their heads but you will also have a bright lightnside.
