All I remember about "Gog and Magog" was a thick yellow book we studied at the weekly book study in the mid 70's. That has got to be the most terrifying book I've ever read... I believe the title was something like "A Thousand Years (... ? ...)". Anyways, I was around 10 or so and I remember having constant nightmares about getting swallowed up by the earth at Armageddon because I had participated in a few "birthday parties" at school. Because of this, I was constantly falling asleep in class after being awake nearly all night or waking up at 3AM after yet another Armageddon nightmare... what a f==ked up cult!
Anyway, that's my 2 cents about "Gog and Magog"...
