The devil is not bound right now,for if he was then there would be peace among people,and also since mankind has a choice between good,and evil,because of Adam,and Eve,eating from the tree of the knowledge of good,and evil,then the devil will not be bound,until mankind does not have that choice,between good,and evil,which is when Jesus takes over the world,and rules with a rod of iron.
The Bible says that Satan is the prince of the power of the air,and he walks to and fro,through the earth,seeking whom he can devour.
As long as mankind has a choice,and still rule kingdoms on earth,the devil will not be bound.
The world will fight against Israel,in which Jesus will save them,and when Jesus takes over the world,and the devil is bound for 1000 years,this is what happens.
Jesus,and the saints will rule over one sixth of the people,that fought against Israel,that God spared.
In that day there will be one LORD,and His name one,which people will only recognize Jesus as God,and the earth shall be full of the knowledge of the LORD.
The people that God spared,have to go up year,after year,to Jerusalem,to worship the LORD.
The people that God spared will live in peace,and not wage war,and animals will eat vegetation,and animals will live in peace,with other animals,and with people,to where a child can lead the most ferocious animal on the planet that exists today.
This is what happens when the devil is bound,for the Bible says he is not deceiving the nations,so when the devil is not influencing the nations,there is peace,which we have not seen these accounts in the past,nor could we,for he has not been bound yet,for if he were there would be peace.
The people that God spared that fought against Israel,still have punishment coming,for they took the mark,which there is no repentance after that,but God spared them so Jesus,and the saints,could rule over them.
So they still have punishment coming,but God postponed it,and at the end of the 1000 years,the devil is loosed from the bottomless pit,and stirs them up to go against Jesus,and the saints,and when they do,God rains fire down on them,and consumes them.
So when the devil is bound,there is peace,which we have not seen that yet,and that is why the people are stirred up to go against Jesus,and the saints,because the devil is loosed,and stirs them up.
So that must be the purpose of the devil being bound for 1000 years,instead of going to the lake of fire during that time,to stir up the people that Jesus,and the saints,rule over,so they will go against Jesus,and the saints,and then God can pour out His punishment upon them,for talking the mark of the beast,and following the beast.
When the devil is bound,there is peace,people do not wage war with each other,so the devil has not been bound yet,for people have been waging war all through history,and if they were not for a time,it would by chance,because they do like to war,and it was not for 1000 years period that they did not war.
