And if a person gains more knowledge and intelligence in this life through his diligence and obedience than another, he will have so much the advantage in the world to come. Doctrine and Covenants 130:19
"Profound spiritual truth cannot simply be poured from one mind and heart to another," said Elder Richard G. Scott of the Quorum of the Twelve in the October 1993 general conference. "It takes faith and diligent effort. Precious truth comes a small piece at a time through faith, with great exertion, and at times wrenching struggles. The Lord intends it be that way so that we can mature and progress."
