Spiritual warfare is an often misunderstood or neglected aspect in the preparation for missions. This session will briefly overview the Biblical understanding of spiritual warfare and examine how our Western worldview (which is not entirely Biblical) is often limited in addressing the broad needs present in a host culture. As some illnesses may be spiritual in their origins, an appropriate understanding and application of spiritual warfare can bring a comprehensive view to treating illness. Also, some basic weapons necessary to prevail in warfare will be presented.
