Wickedness is not merely external behaviour — it originates in desire. The wicked person's soul craves evil, and that inward desire shows up in their treatment of neighbours: indifference, hostility, and an absence of kindness. Sin is a heart problem before it is a behaviour problem.
Memory phrase: Guard what your heart desires.
Talk about it: How does what we want in our hearts change how we treat people?
Prayer: God, fill my heart with good desires.
