Oh, your welcome; and since you know of the LDS world -- (do you represent it?) -- then we can very well consider these Spencer W. Kimball quotes to be as "representational" as you can get for Mormons & Mormon "prophets," right?
LDS President/"Prophet" Spencer W. Kimball in official LDS periodicals proclaimed:
"Man can transform himself, but he has in him the seeds of Godhood that can grow. He can lift himself by his very bootstraps" (Tribune, Sept. 18, 1974).
"Brethren, 225,000 of you are here tonight. I suppose that 225,000 of you may become gods" ( The Ensign, November 1975, 1980).
No, I would draw a distinction between the LDS world and the LDS church. I’m talking about the cultural value of the book. People’s cultural understanding of what Kimball said and did is much different than his position in the LDS church. I would certainly place the quotes you cite as important ones in the culture, and likewise it is important to understand the difference between the culture and the church.
