The Battle of the Mind: Our Thought Life & Our Armor Part 4 by Dr. Frederick K.C. Price teaches that believers face spiritual warfare against unseen forces, not physical enemies. Drawing from Ephesians 6:10–17, he emphasizes the importance of putting on the whole armor of God and standing firm against the enemy’s attacks. Price highlights that knowledge of God’s Word is a believer’s greatest defense, enabling them to recognize and overcome deceptive thoughts and spiritual opposition.
