Ephesians 6:12 names the enemy with precision: not flesh and blood, but principalities, powers, rulers of darkness, spiritual wickedness in high places. Paul wrote this not to generate fear but to correct targeting. The people who exhaust themselves fighting other people — spouses, coworkers, cultural opponents — are fighting the wrong battle. The human beings in your life are not the source. They are often the vehicle.
Charismatic theology has always taken the reality of evil spirits seriously, not as folklore, but as a straightforward reading of the Gospel accounts. Jesus cast out demons as a regular feature of his ministry. He gave his disciples authority to do the same. The commission in Luke 10:19 — "I give unto you power to tread on serpents and scorpions, and over all the power of the enemy" — was not a limited-time offer that expired with the apostolic generation.
The armor of God in Ephesians 6 is almost entirely defensive — helmet, breastplate, shield, belt, shoes. Only one piece is offensive: the sword of the Spirit, which is the Word of God. Spiritual warfare is not primarily about aggressive spiritual combat. It is about standing. Paul uses the word stand four times in six verses. Your position is already secured. Your task is not to take new ground — it is to hold what Christ has already won.
