"One day the evil spirit answered them, 'Jesus I know, and I know about Paul, but who are you?'" - Acts 19:15
Are you a threat to the kingdom of darkness? If satan and his demons had a board meeting and your name came before the board, what would they say? Would they say that you are one of their most feared enemies and they needed to keep many demons harassing and opposing you? Or would they say, "Gentlemen, this person poses no threat to our activities. Leave him alone. He needs no help from us." There are millions of church-going believers sitting in pews Sunday after Sunday who pose little threat to the kingdom of darkness.
If we truly believe that we war against rulers and principalities that cannot be seen, then we must realize that their mandate is to hinder any believer who is seeking to walk in the fullness of God. However, "greater is He that is in you, than he that is in the world" (1 Jn. 4:4b KJV).
If you are seeking to fully follow the Lord, you can expect harassment from the enemy. God permits temptation because it drives us deeper into the soil of God. These times reveal God's power to keep us and walk us through the temptations. Our message becomes fruitful when it is born out of obedience and suffering for His name. Do not consider it strange if you find yourself fighting major battles the more obedient you become to the Master. God desires each of us to become a feared enemy of hell in order to affect satan's domain. When you begin to feel harassed, chances are you are beginning to affect the kingdom of darkness, and satan doesn't like this. So, how many demons do you think are assigned to you?
