"For though we live in the world, we do not wage war as the world does. The weapons we fight with are not the weapons of the world. On the contrary they have the divine power to demolish strongholds." v 3-4. Why is it that us church folks think we can solve the issues we face through the methods of the world around us? It seems over and over we try tackle the problems we face in the church from with an approach learned not in Scripture but in the thousands of other books available to us.
Now I am not saying we should not read secular books. I am not saying there is nothing to be gained from studying the way our world solves problems. What I am saying is those solutions will only give us earthly results. At some point there needs to be a recognition of the battle we are in. I do not want to over simplify, nor do I want to give too much credit to Satan, but the battle we have is the the battle of God and Satan. Our glorious promise is the battle has already been won. Our glorious challenge is we have not yet reached the time of the fullness of that promise. So now Satan is waging war with God, and we are the objects of that war.
We must not use only the techniques and weapons of this world, we must use what God has offered to us in Scripture. We are taught in Scripture how to deal with strongholds. It is not in the name of any earthly authority, it is in the name of Jesus. Time has come for the people to take Paul's words seriously, we are to use the weapons of God in this battle. They are not the same as the ones an earthly understanding offers.
