5 For thus saith the Lord—I, the Lord, am merciful and gracious unto those who fear me, and delight to honor those who serve me in righteousness and in truth unto the end.
6 Great shall be their reward and eternal shall be their glory.
7 And to them will I reveal all mysteries, yea, all the hidden mysteries of my kingdom from days of old, and for ages to come, will I make known unto them the good pleasure of my will concerning all things pertaining to my kingdom.
8 Yea, even the wonders of eternity shall they know, and things to come will I show them, even the things of many generations.
9 And their wisdom shall be great, and their understanding reach to heaven; and before them the wisdom of the wise shall perish, and the understanding of the prudent shall come to naught.
10 For by my Spirit will I enlighten them, and by my power will I make known unto them the secrets of my will—yea, even those things which eye has not seen, nor ear heard, nor yet entered into the heart of man.
Now note the following:
"Oh, ye elders of israel, hearken to my voice, and when you are sent into the world to preach, tell those things you are sent to tell; preach and cry aloud, 'repent ye, for the kingdom of heaven is at hand; repent and believe in the gospel.' Declare the first principles, and let mysteries alone, lest ye be overthrown. Never meddle with the visions of beasts and subjects you do not understand." (Teachings, p.292.)
With this understanding, we can understand why President Hinkley is not quick to answer questions posed by reporters, and Brother Millet instructed his class to answer deep doctrinal questions with first principle answers.
We can easily forgive a child who is afraid of the dark; the real tragedy of life is when men are afraid of the light. - Plato
