If you find yourself laughing at the misfortunes of others, you should examine your heart critically. Do you feel better now that you know someone else is not happy? Are you happy that you’re not the only one unhappy? A case of ‘misery loves company’?
How do you think God feels when you’re hurt? Do you think he laughs?
Your ‘enemy’s downfall is not proof of your righteousness.
“Don’t rejoice when your enemies fall; don’t be happy when they stumble.”
