Satanism is very real, folks, and is everywhere. And while teenagers are frequently inducted into the lastest "groups", there is a much deeper level involvement by committed followers.
Can they get into our churches? Inside the walls of our buildings, yes, and they are already there. In fact, I was present in a church a few years back when a woman on the back got up and began dancing. This was not a worshipful experience - it was a demonic summonsing. She was placing a curse on the pastor (as he himself later confirmed). This was in NC.
