The Spirit-Filled Life (20) - Spiritual Warfare (1) Malcolm Duncan teaching from 1 John 2:15-17 &&name; Ephesians 2:1-3 on "The World". Outline: In opposition to the believer are three foes - the world, the flesh and the devil. It is important for us to understand the enemy we face. A fallen world directed by sinful man has resulted in a system that rejects God and seeks to operate apart from Him. In coming to Christ we become a new creation, and yet this does not remove the battle with the world.
