The Bible gives us a good list of invisible enemies.  It is our duty to believe the Word of God and fight every single one of them until we crush them under our feet. Do not under-estimate the reality of the spirit world.  The spirit world is the real world. This world is the temporary (unreal) world.  Here is a list of invisible enemies you must expect to encounter while you live on this earth.  Jesus Christ did not go far before He encountered devils.  He encountered devils throughout His life and ministry on this earth.
