Imagine there's a kid at school who isn't your friend, someone who sometimes even annoys you. One day they forgot their lunch and they're hungry. What do you do? Proverbs says: share your lunch. Not because they deserve it, but because you're generous.
And you know what happens? They're so surprised by your kindness that they start thinking about what they did. Kindness does something that fighting never does. Jesus did this at the highest level: he healed the people who came to arrest him. And on the Cross he asked forgiveness for the very people killing him. That's the strongest thing there is!
