Yeah it's definitely a good idea to avoid them. They were showing a commercial in the church during a testimony of an ex witch and the commercial showed two people using a wiji board.(or however you spell it)I agree its not too good to watch things like that. I don't watch anything about any ghosts or spirits except the Holy Spirit, Christian shows. Otherwise like you said, it can sure open the door to lots of trouble!
It is interesting about how they believe they can capture this though, seeing spirits are in a different realm . But how a instrument could capture the voices of the spiritual realm is beyond me and makes me wonder if they just opened themselves to the spirit realm and are hearing familiar spirit, which we are to avoid.
And they actually did it... And they made fun of it. Exposed themselves up to demons and everyone in the church! And everybody goes and laughs... Don't they realize that kids will try anything? Kids and other curiosity seekers will see this and want to try it. They've just opened up a door to themselves (the ones doing the weeji game attracting demons) and a door to everyone who saw the commercial.
