What does the phrase "heap coals of fire" signify in terms of responding to an enemy?

The phrase "heap coals of fire" signifies treating your enemy with kindness as a means of overcoming animosity. This expression originates from a biblical context, specifically found in Proverbs 25:21-22, where it suggests that by doing kind acts for one's adversary, one not only demonstrates moral superiority but also has the potential to provoke feelings of guilt and shame in the enemy. The imagery of coals of fire metaphorically represents the idea that kindness can create a burning awareness in the heart of the person receiving it, leading them to reconsider their hostility. This approach aims to transform conflict into reconciliation, highlighting the power of forgiveness and compassion rather than retaliation or bitterness.
