MacArthur is indeed helpful in dealing with spiritual warfare as a present reality. Unlike many Pentecostals who talk about spiritual warfare, Dr. MacArthur takes us back to the Bible. Ephesians 6:11-12 tells us to "Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of the world, against spiritual wickedness in high places." MacArthur's approach from the Bible stands in sharp contrast with the nonsense we hear from our Romish and Pentecostal friends when they talk about spiritual warfare.
