Good knowledge for deliverance ministry and starting one in a church. A little commercial-y for Cleansing Stream Ministries (which seems have a really great basis at the time of the writing, and I do like that their model is communal in nature). The author doesn't elevate those who do deliverance ministries, and the focus is on confession of sin and giving glory to God v. glory to self. I didn't agree with everything, but I thought this was a good place to start.
