You played Dungeons and Dragons??? Oh my gosh thats getting into Satan's territory. Why did you do it? You may have invited devils into your life.
This might comes as a shock to you, as I'm someone who has been involved in ministry for 12 years, but I've played it, too. I was even Dungeon Master for our group, as I'm one of the better storytellers in my group of friends. There's no "satanic" connotation to our games. The characters we invented were just for fun. The dungeons and puzzles they had to overcome were just for fun.
We didn't meet in secret and hold a black mass before busting out the satan shrines. We sat around a table, mostly relaxed. We might have a map or a something that I had drawn up to further the game. Whenever the group would try to go somewhere that I, as DM, didn't want them to go, I could change the story to force them back onto a course I had chosen. Basically, D&D is the JRR Tolkien version of "choose your own adventure."
As someone else said, if you start labeling everything as "satanic," you being to tread shaky ground. You could call the writings of C.S. Lewis "satanic," even though he arguably held to a Christian point of view. Tolkien's "Lord of the Rings" is pure fantasy, but it carries Christian allusions. I wouldn't label those things as "satanic" just because they're not overt glorifications of Christ.
In the book Lutzer tells story after story of people whom committed suicide or killed someone else after playing that game.
Guess what, evangelist? People have committed suicide after going to church. People have killed other people at church. Does that make church "satanic?"
Lutzer was right Satan has indeed invaded the church.
I believe Satan can invade anything, if given the opportunity. Invading a church is a trophy for him. I could point to several "mainstream" mega-churches and give you good examples of why I think Satan has invaded them. We can tackle fictional elements of the world once we clean out the spiritual household.
Satan will invade a person's life if they allow it. It requires a level of will power on the part of the person to not allow the cracks to form in which Satan can break through, and it requires a reliance on the Lord to keep them safe.
