What's a Legal Right?

During a deliverance the devil will claim that the person either has sin or iniquities that give them legal rights to be in a person. These must be broken before a person can be totally delivered. A demon that has legal right can be cast out; however it will return immediately into the person with 7 worst than itself because it will claim legal right to be there. Unless the legal right is broken, the demon can claim his right, and God will honor it.  

2 Timothy 2:24-26

24 And a servant of the Lord must not quarrel but be gentle to all, able to teach, patient, 
25 in humility correcting those who are in opposition, if God perhaps will grant them repentance, so that they may know the truth, 
26 and that they may come to their senses and escape the snare of the devil, having been taken captive by him to do his will.

This passage of the Bible clearly illustrates how a demon can have legal right upon a Christian. We know that he is speaking about a Christian, because Paul is instructing Timothy on how to deal with the congregation. In these verses we have the Apostle Paul instructing Timothy on how to deal with those that have opposed themselves to God. He is to treat them with gentleness. God may perhaps grant them repentance leading to to a knowledge of what is true.  These people have fallen into error, because they have been deceived by the devil. Their sin is that they opposed God, as a result the devil treats them like puppets. By Timothy treating them with gentleness, they may repent of their opposition against God.  And then maybe they will come to their senses and escapes the traps of the devil, after being captured by the devil to do his will.
