See especially chapters 17 - 24, for those who are interested. Basically, this is Ellen White recounting in her own words the Millerite movement, the Great DIsappointment, and how she and others would never accept that he was wrong. IT's a truly bizarre thing to read. It's basically someone cutting and pasting verses from the Bible, and using flowery language for pages and pages, to prove that black is white. And false is true. -- After a time of intense seeking and re-studying the chronology, guess what conclusion they came to? The Second Advent did indeed occur in 1844, but.........IT WAS INVISIBLE!! Hmmm, sound familiar?
Some recurring themes I noticed were:
churches bad, us good
Our group, or individuals in it are....people or prophecies in the Bible! Like, we're the wise virgins. And some guy's prophetic chart was the fulfillment of a prophecy in Habakkuk! LOL.
"new light" "more light" "clearer light"
Those who got disillusioned after the false prophecy lacked faith, were worldly, couldn't endure, etc. God used the false prophecy to 'test' people, and weed out those with bad motives.
