A selection from the 2017 book,
(From the chapter on Elder McConkie’s special witness of Jesus.)
On June 1, 1978, Elder McConkie enjoyed, with his Brethren of the First Presidency and ten of the Twelve, the most spiritual experience of his life, at least to that point. It came in the House of the Lord at the time of the receipt of the revelation to President Spencer W. Kimball extending priesthood and temple blessings to all worthy men regardless of race (see D&C Official Declaration 2). On June 28, 1978, Elder McConkie related the event to family members while vacationing in Nauvoo, and visiting in the home of a Kimball relative. A family member present that took notes from Bruce’s narration later described what he said:
When we were all seated . . . Bruce began to tell us some of the events and details about this revelation. . . . One thing that he cautioned us not to do was to make it more than it was, even though I can’t imagine a greater thing than this in this life. . . . With President Kimball the preliminaries for this [revelation] started at least two years [before it was received]. There were many, many, discussions, returning to the subject from time to time in their quorum meetings in the temple. There was much fasting and there was much praying and many prayers were offered pleading to the Lord for a resolution of this problem. During the last three or four months there had been extended discussion during the quorum meetings regarding offering all of the blessings of the gospel to all the people of the earth.
Now the various members of the quorum were asked to express themselves briefly and did. . . . The Prophet had told the quorum that this was a problem that he had been wrestling with for many hours and had spent many hours going to the upper rooms of the temple, wrestling [in prayer] with the Lord. He had not received a revelation but he wanted a revelation. . . .
This particular Thursday (this was on June 1st) President Kimball asked the members of the Quorum [of the Twelve] to stay; he said that he had some things that he wanted to discuss further. All of the members of the quorum were there except [two].
