To mock someone who is poor is to insult their Creator, because every person is made in God's image and carries His worth. Equally, taking pleasure in another person's suffering or disaster — a form of cruel pride — will not go unpunished. God is the defender of the poor and the afflicted, and He takes personally the treatment of those made in His image.
Memory phrase: God made the poor.
Talk about it: Why is mocking someone poor the same as insulting God?
Prayer: God, help me never mock those who have less.
