Heap of burning coals

This morning, I received a devotion note....

Romans 12:20 - "If you enemy is hungry, feed him; if he is thirsty, give me something to drink. In doing this, you will heap burning coals on his head."

A verse in Proverbs 25:21-22 :
"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:..

These words - heap of burning coals have kept me thinking for the day.
Tonight, I turned to my study bible for these words...

The above commands sounds almost impossible. Why Paul commanded it? In this study bible, forgiveness is the key to above verses. It said, when someone hurts you deeply, instead of giving him what he deserves, befriend him. Forgiveness may break a cycle of retailation and lead to mutual reconciliation. It may make the enemy feel ashamed and change his or her ways. By contrast, repaying evil to evil hurts you just as much as it hurts your enemy. Even if you enemy never repents, forgving him or her will free you of a heavy load of bitterness. Lastly forgiveness involve both attitudes and actions. Appropriate actions may send a signal of restoration of relationship and lead to right feelings....

Dear Lord,
Thank you for your words tonight. I ask for your forgiveness that I have judged people over their testimonies who glorify themselves more than glorifying You. Lord, forgive me and help me to have a forgiving spirit too. Heaps of burning coals not only telling me about forgiveness, it also tell me about kindness.. Lord, help me to simle and keep my spirit quiet for the least when I am with some unpleasant people.... Lord, help me and teach me Your ways to have a right attitudes and actions in all relationship matters...... Amen
