Lewis Sperry Chafer said next to the person and work of God, spiritual warfare is the doctrine of most importance. Spiritual warfare is not a flat tire in rush hour—give Satan more credit than that. It is subtle, often easily camouflaged in human relationships, areas of discontentment, unbridled pride, and non-sanctified priorities. Any area of our life not submitted to God is an arena in which the devil looks for a foothold.
