If you are a Christian, then you are in a war, but you are not alone. Even better, you have Jesus Himself praying for you. But He is not praying for you to leave the battle. In fact, He calls you to it. One particular battle you must fight is against the world, and the weapons of the enemy are not conventional. Dr. Sproul explains to us what those weapons are as he prepares us for "The Battle with the World."
