Jesus delegated His authority to His people to trample on all the power of the enemy (Luke 10:19).  Therefore, satan and his minions have no grounds upon which to invade your life except for what you give them.  But the good news is, if you have given satan ground in your life, you can also take that ground back.  This teaching identifies two areas where believers give satan access points in their lives where the forces of darkness exert influence and harass God's people, and how to free one's self from those strongholds.
