¹⁹You believe that God is one. You do well. The demons also believe—and shudder.

James 2:19World English Bible, Protestant Edition

The scene

The preceding line challenges a person to show faith without works and offers to show faith by works. The next calls faith apart from works dead.

What does the example of the demons add to the challenge to show faith by works?
