The Battle of the Mind: Our Thought Life & Our Armor Part 2 by Dr. Frederick K.C. Price teaches that the mind is the primary battlefield where spiritual warfare takes place. Drawing from Ephesians 6:10–17, he explains that believers must guard their thoughts against doubt, fear, and deception by putting on the whole armor of God. The message emphasizes that spiritual victory comes through renewing the mind with God's Word and standing firm in faith against the enemy's attacks.
