There are three things that if you study in life, I guarantee you, you won't die small. The first is how to hear God, the second is faith, and the last but not least is spiritual warfare. The devil knows he's been defeated at Calvary. Paul painted this picture for us when he told us that Jesus made a public spectacle of satan and his cohorts in hell. The problem is satan knows, but his nature is rebellion. Therefore, we must engage spiritual principles in fighting from the place of victory already secured at Calvary
