Do you blush?

Wildman, and resident philosopher from Denver Seminary, Dr. Doug Groothuis says,

Truly, too many Americans have lost the ability to blush--a prelude to judgment if not repented of. Read Francis Schaeffer's Death in the City on the judgment of God against the West and what this means for Christians. We need more weeping prophets (like Jeremiah adn Schaeffer), not wimpy puppets. See Jeremiah 20:9
