Okay C, you got me to bite, that is what you want.
Let's check out the Word and see what the Word says.
Act 16:16 And it came to pass, as we went to prayer, a certain damsel possessed with a spirit of divination met us, which brought her masters much gain by soothsaying:
Act 16:17 The same followed Paul and us, and cried, saying, These men are the servants of the most high God, which show unto us the way of salvation.
Act 16:18 And this did she many days. But Paul, being grieved, turned and said to the spirit, I command thee in the name of Jesus Christ to come out of her. And he came out the same hour.
This is a great example of the discerning of spirits.
The spirit was compelling or controlling this woman to say the right thing but Paul knew, through the gift, that it was coming from a spirit.
He discerned that it wasn't God's spirit but an unclean spirit that was working here.
This is a great example, Biblically, of the gift of discernment of spirits.
