Consider what it is to command someone to do something, and how this applies in the spiritual realm.
The demons tried to tell Jesus what to do by calling on his name and giving a command.  This is the same equation, with different people as the variables.  I, talking to my friend Carlos, could specify who I am talking to (ie. Call on his name “Carlos”) and if I had the authority I could give a command.  “Carlos, stand up.”  I must have the authority in that place, over him, in order to order him what to do.  He may give me that authority and obey, or I may take it by force.  I might command an individual with their name, or a collective if the collective was named as a group.  “Stand up, church.”
Consider what it looks like when the person is not in the place, they can’t hear you.  They are not able to receive communication of what the command is.  This is the sense in which “place” is required, and also a connection of some kind.  A spiritual connection is required for commanding a spirit — they must “spiritually hear” your command.
One must be in the same place.  In the opening chapter of Luke’s Gospel, Jesus was in the same material place as these demons.  A person must be in the same place, spoken (or some form of communication, spiritual or material) in order to command someone.  This is the means by which scripture has power – when it is read.  That is the sense in which place matters to the authority of scripture, and by which these written words can communicate, they bring life when it is read.
What happened in the book of Luke, chapter 1 and 2 was a power encounter.  The demons were trying to control Jesus, but they could not, and so they resorted to what is essentially a spiritual negotiation.  Let us have this place, they request, or these material bodies.  The demons actually *could* have controlled Jesus by speaking his name, if they had the authority.  This is what they were trying to do when they brought Jesus’s name into it.  A name is an identity, in the sense that it may be called upon.  A name is a means to intimacy, and in that it is a means to control.  In knowing a persons’s identity, that person may be controlled.  This was the sense in which there was a power encounter in the casting out of demons.  This was the demonstration of Jesus’s authority: they knew his identity, and it did not matter as far as their competing agenda’s were concerned.  Jesus’ agenda won out because of his authority.
The disciples go to a place to cast out demons, to do the work.  The disciples had place.  And the demons had a material place.  Consider what it is to find a spirit.  Spirits have material place.  The way in which we bring a spirit into a place, in which we can recognize it, is to call their names into a place.  The act of calling a name has a place, and it brings spirits into a material interaction, in a place.  The disciples had a place where they went, and brought the authority of Jesus into a place.
Authority has a place. It travels with material persons sometimes, or authority stays in a place.  The authority of Jesus is… where?  Is it in you? Is it in your city?  Then speak it into being.  To communicate, to read the word or to speak the name of Jesus is to connect material and spiritual.  It accomplishes authority.
We call Jesus’s authority into a place, and by speaking this in a place, we bring in the authority of God by his name into that place.  When we do this, God’s authority meets us in that place, his power meets us in that place, we speak it into existence.
