Many of the most important principles of intelligence cannot by taught at universities, from books, or through other temporal learning processes. Often these great principles are learned from afflictions, tribulations, and other mortal experiences. All that we learn in this manner will benefit us not only in this life but also in the next, for 'whatever principle of intelligence we attain unto in this life, it will rise with us in the resurrection'.
We must each prepare ourselves for every good work that might come to us and then accept the principle that revelation, not aspiration, is the basis for our respective callings.
I suggest that all who listen to my voice would benefit by an examination of the lives of those we sustain as general officers of the Church. You will find some important examples among them and come to know those who have "a perfect heart."
