Apostle Paul and a slave girl

 As we were going to the place of prayer, we met a slave girl with a spirit of divination, who used to bring a large profit to her owners through her fortune-telling. 

She began to follow Paul and us, shouting, “These people are slaves of the Most High God, who proclaim to you a way of salvation.”  She did this for many days. Paul became annoyed, turned, and said to the spirit, “I command you in the name of Jesus Christ to come out of her.” Then it came out at that moment. (Acts. 16:16-18)

Notice Paul did not not have her pray the sinners prayer or sign her up for counseling.  No, he cast the demon out of her.

If you read the full account of this story you will see that this got Paul and Silas in lots of trouble.  They got beat and thrown in jail and accused of throwing the city into confusion.  The Devil does not take kindly to Christians casting the demons out of his people.
