I have read many of your bible studies . I am confused as to parts of the studies are associated with Ellen White. Did these studies come from Books on her studies? So much of what I'm reading seems to line up with so much scripture but the dates of May 19th 1780 & Nov 13, 1833 do not add up to what I see in the word of God and the history that I looked up had explanation for those days which when I compare to the word The tribulation has not even started as yet. Could you please give me some more information on these dates? I am confused about why the bible studies have Ellen Whites findings is she a prophet that bible students base some knowledge on? Where does she fit in on these studies?
