A couple of verses of Scripture that are crucial to understanding this:
Remember, a wolf does not usually come out and say, "I'm a wolf!" Yet, they will tell you who they are if you watch them over the long haul. A wolf will use people until they have had enough and then kick them to the curb, hurt them and leave them wounded. The true shepherd comes along and tends to the wounded sheep. Sadly, those that are prone to following wolves will usually go back and follow them over and over and over, because they come with enticing words and flattery that builds the sheep up and makes them feel good... until they are ready to kick them to the curb again. Yet, they will follow them again and again, allowing the wolf to mistreat them... because they like the sweet lies they speak to them for a season... and even a season of bliss seems worth it to those that are prone to follow the false shepherd.
