The only thing I can think of off-hand is James 2:19 – “You believe that there is one God. Good! Even the demons believe that—and shudder”, but that doesn’t quite answer your question. The general belief is that all non-believers will face the same judgment. Most Satanists are Atheists anyway, they just believe in the “concept of Satan”(basically an excuse to have promiscuous sex, use drugs, and do goofy “rituals” with goat blood), but not an actual Satan. But I’d rather deal with an Atheist because LaVeyan Satanists are basically douchebag goth kids and true Satanists like to kill cats.
