The driving motivation for many Christians who are heavily involved in doing spiritual warfare against territorial spirits is their desire to see God’s kingdom expanded. For this they are to be commended. Every Christian should desire to see more people escape from Satan’s grasp.
It is important, however, that we use God’s methods to build God’s kingdom. God knows what works and what is a waste of time. He has told us exactly what our responsibilities are in regard to the expansion of His kingdom. To think we can do something not found in Scripture that will multiply the effectiveness of our evangelism, something that Jesus, Peter, or Paul never practiced in their ministries, is foolish.
Why do so many Christians think that spiritual warfare can open the door to effective evangelism? Their line of reasoning usually sounds something like this: “Satan has blinded the minds of unsaved people. We must therefore do spiritual warfare against Satan to stop him from blinding them. Once the blinders are removed, more people will believe the gospel.” Is this true?
There is certainly no doubt that Satan has blinded the minds of unsaved people. Paul wrote:
And even if our gospel is veiled, it is veiled to those who are perishing, in whose case the god of this world has blinded the minds of the unbelieving, that they might not see the light of the gospel of the glory of Christ, who is the image of God (2 Cor. 4:3-4).
The question is, Did Paul give this piece of information to the Corinthian Christians with the intent of motivating them to do spiritual warfare and pull down territorial spirits so that unsaved people would become more receptive?
The answer is No for several obvious reasons.
First, because Paul did not go on to say, “Therefore Corinthians, because Satan has blinded the minds of unbelievers, I want you to do spiritual warfare and pull down territorial spirits so those blinders will be removed.” Rather, the very next thing he mentioned was his preaching of Christ, which is the way that spiritual blindness is removed.
Second, in none of his letters did Paul instruct any believers to be involved in pulling down strongholds over their cities that evangelistic results might increase.
Third, we know from reading all of Paul’s letters that he did not believe Satan’s blinding was the primary reason why unbelievers remained unbelieving. Satan’s blinding is a contributing factor, but not the main or only factor. The primary factor that keeps people unsaved is the hardness of their hearts. This is obvious for the simple reason that Satan is not able to keep everyone blinded. Some people, when they hear the truth, believe it, and thus reject any lies they formerly believed. It is not so much Satan’s blinding that causes their unbelief, as it is their unbelief that allows Satan’s blinding.
