“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.”
Do not be overcome by evil, but overcome evil with good.
~ Romans 12:20-21
Generosity confuses adversaries. It doesn't make sense that a man would offer to help someone who intends to do him harm. That is why it's so effective!
The ways of God runs against the grain of the world. If you truly want to overcome evil, then find a way to bring God into the room - inject Him into the conversation. Show God's love to those who are difficult to love.
Think of one enemy or adversary you face right now. How can you show kindness without showing weakness? Pray for them, serve them, greet them.
