Binding Principalities and Authority over Territorial Spirits

Has anyone participated in this kind of spiritual warfare? If so, I'd love to hear your story and what happened.

Check out what this guy, who said he's done it, said about it: "When I participated in this type of so-called spiritual warfare I found my career interupted. I lost my first job after completing my graduate degree. I wandered in a vocational desert for a few years. I was not able to save money. I could not fulfill my career aspirations. I returned to live with my mother and worked in a warehouse.
I now believe that I exposed my career and finances to enemy attack when I undertook aggressive and arrogant spiritual warfare involving binding territorial spirits.
Such prayer removes a Christian's normal protection or "hiddedness in Christ." Exposure to the enemy is the result. One impact of exposure is that God's supply in terms of career and finances is reduced to a trickle."

I guess he couldn't handle the heat! Of course you're going to get attacked when you fight the enemy! What did he expect, no persecution?
