You asked, "In James it says the demons believe,,,,are they saved?".
In eternity past the demons choose to side with Satan.
So I guess it is more than just belief..I guess it would be a choice to obey as well.......
Well, perhaps the thought of RECEIVING Christ instead of just believing he existed and fearing him, as demons do, will clear some of that up. You ASK Him to come into your life to save you. Demons haven't done that. They are fallen angels who were kicked out of heaven.
