As we move through scripture we should take notice of the names given to the deceiver. We must look into his purpose and realize that our battle is not with the flesh but with the spirit. For we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places. (Ephesians 6:12) The deceiver uses the fallenness of people to do his bidding and cover his involvement. We get so focused on the person we see, we forget the spiritual battle that is at work. Know your enemy! Know your Savior! Focus on God and His promises. Be the victor in the battle for your spirit!
