Martha Nussbaum says we don't. She's wrong.
We have a culture of nice that allows bullies to flourish. I have watched as this culture allowed certain people to take over a church. Then the group placates that person, and even asks the person who stands up to the bully to sit down, in order to maintain peace. This dynamic can and does kill churches.
Hardness of heart. Scripture uses this image to describe those who are impenetrably stubborn, those who are unwilling or unable to see God’s glory or to reorient their lives to God’s call and claims. But what causes hardness of heart? Is it always human sin, those things which we have done which ossify our hearts and rigidify our minds? Do tragic accidents sometimes harden us in ways that make it difficult, if not impossible, to remain open to transformation, to sustain a mental, emotional and moral agility?
