In episode #31, Claire discusses spiritual warfare and resisting attacks of the enemy. 

"Watch out for your great enemy, the devil. He prowls around like a roaring lion, looking for someone to devour. Stand firm against him, and be strong in your faith."

1 Peter 5:8-9

"For we are not fighting against flesh-and-blood enemies, but against evil rulers and authorities of the unseen world, against mighty powers in this dark world and against evil spirits in heavenly places."

Ephesians 6:12
