Spiritual Warfare Definition
Some Charismatics use the phrase 'spiritual warfare' for actions they believe fight demonic powers. This type of behavior is completely unrelated to resisting the devil spoken by the apostle Paul in Ephesians 6.
The apostle Paul, in his many letters, does use references related to human warfare as symbolic of what must be done in the spiritual realm (2Corinthians 10:3-5, 1Timothy 1:18, etc.). He defines spiritual warfare in two parts. First, true believers have an ongoing war within themselves between their self-defeating human nature that leans toward sin and the influence of God's Holy Spirit that guides a Christian toward righteousness.
Paul second part of spiritual warfare is that of refuting false teachings and 'bringing into captivity every thought into the obedience of Christ' (2Corinthians 10:5).
Charismatics, however, have a different version of what it takes to battle in the spiritual realm. For them, combating evil involves over-the-top affirmations by a religious leader, where countless audience members declare they possess the power to constrain Satan or his demons in a city. This type of strategy is sometimes referred to as "spiritual mapping."
Bill Randles, in his book Making War in the Heavenlies: A Different Look, takes a critical view of some of the tactics used by those who engage in spiritual warfare. He reveals the steps some take to 'free' a city from the bondage of an evil entity.
