"An incredibly popular subject of discussion in the body of Christ" today is the whole area commonly called "Spiritual Warfare." As one reads the Gospel accounts, it doesn't take long to see there seemed to be much more overt demonic activity in Palestine at the time of Christ than there is in Western culture today.
But that is not true of our world as a whole. Even Western culture is moving away from secular humanism with its emphasis on rationalism and the mind, toward a worldview some have called "cosmic humanism"- a man-centered belief system with the added dimension of the supernatural. This evolving worldview is reflected in the rapid embracing and repackaging of eastern mystic beliefs into what is called the New Age movement.
It seems spiritual warfare is being discussed and taught more now than at any time in recent history. Yet, much of what is being taught today about Satan and demons is erroneous and unbiblical. However, this increased attention given to the subject can be used of the Lord for good in that it can move all Christians to search out the Scriptures and determine what the Word really teaches about Satan and the Christian's response to him. This study seeks to become a partner in this process.
