I recently did a short teaching series on themes related to spiritual warfare for my Sunday school class at church. This is designed to be a basic introduction to the topic. I have based many of the ideas on Karl Payne's book, Spiritual Warfare. and combined it with some of my personal story of being recently healed from multiple mental illnesses.
