This is an old book–out of print but still available used at Amazon.

Agree or disagree with him, Peter Wagner is first and foremost a theologian. His works on Pentecostalism drastically changed the face of Christianity and mission in the 1980s.

I found this book, unread, on my shelf while looking for another. It answers most of the questions I have about the biblical foundations for much that goes on today in the name of spiritual warfare. Read it in a day because I couldn’t put it down. The book strengthened my prayer life.

Much of what we’ve enjoyed in a culture bending prayer movement in Hawaii comes out of what has always appeared to be more experiencial and a little light on theological grounds. Wagner comes to the rescue…

He deals with “identificational repentence,” not just from the book of Daniel but from the New Testament. Territorial spirits and how to deal with them come straight out of the life of Jesus and then his disciples. Paul did some of this too.

Perhaps best is his argument that an argument from silence cuts both ways–in other words silence doesn’t prove that something happened (we all know that) but it also doesn’t prove that something didn’t happen. I call Wagner’s conclusions “tip-of-the-iceberg” thinking. He teaches that if you can find a little of something in the life of the apostles you can reasonably assume that there was more of it. The gospels and Acts don’t record everything they did, only representative moments. A pretty strong argument for a well-reasoned theology of prayer that intends to change the world around.

This book should be in print–thank God for used booksellers.
