Supplement is from Elder Richard G Scott's talk, "Acquiring Spiritual Knowledge" from the October 1993 general conference:
Since it requires much personal effort to gain and use worthwhile knowledge, you cannot endlessly sample from every fascinating arena of life. Therefore, you should select carefully a few vital areas where you can focus energy to learn and share vital truths. I know that to gain knowledge of great worth requires extraordinary personal effort. This is particularly true when our desire is to obtain spiritual knowledge. President Kimball said it this way:
“The treasures of both secular and spiritual knowledge are hidden ones—but hidden from those who do not properly search and strive to find them. … Spiritual knowledge is not available merely for the asking; even prayers are not enough. It takes persistence and dedication of one’s life. … Of all treasures of knowledge, the most vital is the knowledge of God” (The Teachings of Spencer W. Kimball, pp. 389–90).
