"I believe that God uses the gospel to deliver people from the hostile powers and that the gospel effectively accomplishes all God intended to do from all eternity to save sinners. Those who believe are “saved to the utmost” (see Hebrews 7:25) and need not fear the hostile spiritual forces of the universe. The means of grace provided in the Bible are sufficient to cause us freedom and growth in the grace and knowledge of the Lord.
Those pushing the warfare worldview (deliverance ministries) want us to think otherwise. They want us to believe that teachings, techniques, and spiritual processes that were not even conceived until the 20th century are necessary for us to be free from Satan’s bondage. This means we must believe that Christians throughout the centuries lived without freedom because the gospel they believed was insufficient. By convincing us of the insufficiency of the gospel they become bondage makers. I used to be one. I thank God He freed me from that condition through the truth of the Scriptures."
"What this teaching does is make people think that their freedom is dependent on them living a nearly sinless life. Any mess up and the demons come back. To show how much this depends on man rather than God’s grace, consider what Bob Larson says: “I’ve known people whom I refused to help until they matured in the Lord to the point Satan didn’t want them any longer.” Evidently if you are not a good enough Christian you have to keep your demons. This worldview can only result in fear or pride. Fear if you believe that you cannot behave well enough to keep the demons from getting you, or pride if you think that you are such a powerful, sinless Christian that Satan fears you and cannot touch you. These outcomes (fear or pride) are the result of trusting man rather than God."
