I can’t estimate the numbers but to me, the significance of the message of the UB is that if I don’t pay attention, I could get confused and end up not surviving .
Another direct contradiction of the UB….can’t happen!! 
Oh you’re right. I forgot. The UB says Lucifer proclaimed everyone survives no matter what.

Enno – we’ve had this discussion on TruthBook, you and I. You’re doubts as to your own worthiness and survival and that of your fellows for whom you are so concerned. Your lack of confidence in the survival of your soul originates from the beliefs and teachings of other religionists (especially certain so-called Christian religionists). And while your personal humility may be laudable and your uncertainties deserving of tender empathy and patience, still do you contradict the teachings. Non-survival, according to the Revelation, requires very specific knowledge, conscious decision, and knowing rejection of love and mercy….confusion won’t cut it dude.
110:3.5 (1206.3) Confusion, being puzzled, even sometimes discouraged and distracted, does not necessarily signify resistance to the leadings of the indwelling Adjuster. Such attitudes may sometimes connote lack of active co-operation with the divine Monitor and may, therefore, somewhat delay spiritual progress, but such intellectual emotional difficulties do not in the least interfere with the certain survival of the God-knowing soul. Ignorance alone can never prevent survival; neither can confusional doubts nor fearful uncertainty. Only conscious resistance to the Adjuster’s leading can prevent the survival of the evolving immortal soul.
34:7.8 (383.2) Having started out on the way of life everlasting, having accepted the assignment and received your orders to advance, do not fear the dangers of human forgetfulness and mortal inconstancy, do not be troubled with doubts of failure or by perplexing confusion, do not falter and question your status and standing, for in every dark hour, at every crossroad in the forward struggle, the Spirit of Truth will always speak, saying, “This is the way.”
188:4.9 Salvation should be taken for granted by those who believe in the fatherhood of God. The believer’s chief concern should not be the selfish desire for personal salvation but rather the unselfish urge to love and, therefore, serve one’s fellows even as Jesus loved and served mortal men.
Cheer up Enno….it’s not what I say or Lucifer said….it’s the whisper of the Comforter and Pilot within, the Light of Love that lives within and the 4th and 5th Epochal Revelations that should relieve your “confusional doubts” and your “fearful uncertainty”. I’ve always taken you for a Believer Enno. Did you know that well over 90% of Urantians today profess such belief? I wonder can those who believe in a Creator or Great Cause & Upholder, no matter how ignorant or depraved or misguided or misdirected, can they be condemned to oblivion by the God of our Brother Michael as taught by Jesus….the Giver of Life and the Loving Father of All?
Enno…do you truly fear for the survival of your soul? And the souls of others with the Light Within?
If so….then I am very sorry for you Brother, very sorry indeed. I hope you jest or hope to make some point I am too blind to see!
