The world believes that the purpose of having more of anything is to be more capable of controlling others:
42 But Jesus called them to him, and saith unto them, Ye know that they which are accounted to rule over the Gentiles exercise lordship over them; and their great ones exercise authority upon them.
43 But so shall it not be among you: but whosoever will be great among you, shall be your minister:
44 And whosoever of you will be the chiefest, shall be servant of all.
45 For even the Son of man came not to be ministered unto, but to minister, and to give his life a ransom for many. (Mark 10)
The truth is that more truth is good for only one thing: more adequately serving others.
God, seeing he was superior, did and does what he does to provide a pathway for others to obtain the same:
God himself, finding he was in the midst of spirits and glory, because he was more intelligent, saw proper to institute laws whereby the rest could have a privilege to advance like himself....He has power to institute laws to instruct the weaker intelligences, that they may be exalted with Himself, so that they might have one glory upon another, and all that knowledge, power, glory, and intelligence, which is requisite in order to save them in the world of spirits. (“Teachings of the Prophet Joseph Smith,” p. 354).
The Lord ordained those with more light and truth to do the same:
22 Now the Lord had shown unto me, Abraham, the intelligences that were organized before the world was; and among all these there were many of the noble and great ones;
23 And God saw these souls that they were good, and he stood in the midst of them, and he said: These I will make my rulers; for he stood among those that were spirits, and he saw that they were good; and he said unto me: Abraham, thou art one of them; thou wast chosen before thou wast born.
24 And there stood one among them that was like unto God, and he said unto those who were with him: We will go down, for there is space there, and we will take of these materials, and we will make an earth whereon these may dwell;
25 And we will prove them herewith, to see if they will do all things whatsoever the Lord their God shall command them;
26 And they who keep their first estate shall be added upon; and they who keep not their first estate shall not have glory in the same kingdom with those who keep their first estate; and they who keep their second estate shall have glory added upon their heads for ever and ever. (Abraham 3)
There is nothing about being better that is desirable to a carnal mind. From a carnal mindset, it is more enjoyable in every way to be mediocre. The only motivation for being better is love of God and love of your fellowman.
Being “great and noble” is not a joyful thing. It is a burden. It doesn't get you a sports car and a trophy spouse. It gets you the knowledge of why these things are not actually desirable.
Truth gets you more opportunities to suffer without recognition for the benefit of others who do not appreciate you. All who will be better will be undesirable to their fellowmen. They will be despised and rejected. They will be full of sorrow. They will suffer for the sins of others. They will be wounded by others. They will be oppressed and afflicted. In spite of all this, no one will listen to them, and they will be comforted only by the knowledge that they had done all they could.
Holding higher truth is not something to be envied in the lens of the world. To be “great and noble” is to be:
...stoned, sawn asunder, tempted, slain with the sword, and [wander] about in sheep skins and goat skins, being destitute, afflicted, tormented...[To wander] in deserts and in mountains, and hid in dens, and caves of the earth; (TPJS p. 32)
Anyone can give a person what they want. Only a real friend will give you what you need, whether or not you are wise enough to know it.
