"For we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places" (Ephesians 6:12).

What did C.S. Lewis believe about the unseen world?

How do “spiritual forces of evil” affect our everyday lives?

And why does The Screwtape Letters, Lewis’s fictional dialogue between two demons, continue to have such a lasting impact?

Learn to see and live in light of the unseen realm as Lewis saw it. C.S. Lewis scholar and Professor Emeritus of Wheaton College, Dr. Jerry Root, presents two lectures on:

  • “C. S. Lewis and Spiritual Warfare”
  • “C. S. Lewis’s The Screwtape Letters: Big Themes”

The presentation includes a Q&A session. This event was hosted by CSLI Greenville and held on Feb. 27, 2023.
