Saul consulting the witch of Endor

Okay, I have read our McGee commentary. Remember when I said that when you are "playing" a ouija board there is no way to contact your loving Christian grandmother who has passed away. It is ALWAYS evil. But, I had to wonder if God did allow Saul to call up Samuel through the medium. Why would God himself not speak to Saul but allow a medium to give him a Godly message??? And come to find out, the supposed Samuel that spoke, didn't tell Saul anything new. It was what he already had told him was going to happen. And I do know from experience that demons are master impersonators. For those of you who weren't there I admitted that I used to do ouija boards and the nightmarish things that happened. They are very real and always demonic. Even though at first might make you think it's harmless and your talking to an actual nice person who just happened to be dead. And where did it say that the Lord allowed it to happen? Or did we just come up with that theory ourselves? I can't find it in scripture anywhere. And here is another question, was satan able to call up Samuel? No way! Oh, and I found this, 1 Chronicles 10:13, "So Saul died for his transgression which he committed against the Lord, even against the word of the Lord, which he kept not, and also for asking counsel of one who had a familiar spirit, to inquire of it.". So there is the answer. Whew! That's been eating my brain!
