This is an exciting find, thanks for posting it. Kimball is a pivotal figure in the LDS world and this update by his son of his well thought out biography looks very interesting.
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).
