This book tells the story of how God taught me, as a practicing psychologist, to confront demons in my clients. He initiated this activity himself in my office, much to my surprise. During therapy sessions, demons began talking to me through my clients' mouths, wholly unsolicited. This was God's way of forcing me into a ministry for which I was not prepared.

When I asked: "Lord, what are you doing?", his answer was: "I need to use your office; I need a place where I can bring hundreds of persons who are not receiving the care they need. They go to psychologists, psychiatrists, Christian pastors, and Catholic priests seeking help, but these professionals are not discerning that the main problem afflicting these sufferers is of demonic origin. I know you have not been trained in spiritual deliverance, but I will teach you, right here in your office. I will even force the demons to talk to you so that you can understand what this spiritual battle in people's lives is all about."

So, what was I to say?

"No, Lord, I cannot allow you to turn my office into a place where demons are going to manifest?" If he's my Lord, obviously I couldn't say "no". So, I went along with his plan. He taught me how demons enter people's lives through psychological trauma, sin, curses, and involvement in occult practices and, most importantly, how to close those doors and cast the demons out. I share my experiences in this area, and I describe the things I learned through them so that others can understand how to deal with this demonic realm in the lives of those who seek their help.

This book describes how God taught me to see through Satan’s psychological disguises and the remarkable adventure that ensued as he has brought me face-to-face with humanity’s personal enemies in the spiritual realm. He trained me in spiritual warfare that I may teach others, as well.
