You are nothing special. But God is special, and those who seek him with all their heart will be made capable of having an immeasurable impact through obtaining and disseminating his light:
Yea, he that repenteth and exerciseth faith, and bringeth forth good works, and prayeth continually without ceasing—unto such it is given to know the mysteries of God; yea, unto such it shall be given to reveal things which never have been revealed; yea, and it shall be given unto such to bring thousands of souls to repentance, even as it has been given unto us to bring these our brethren to repentance. (Alma 26:22)
Note how the preceding promise is conditioned only on the individual’s adherence to truth and their application of faith.
God calls upon the weak things of this earth to thrash those who think they are mighty. That is the pattern in scripture. Whether it is stammering Moses, or second-string priest Ezekiel, it seems that he has a ready supply of those weak enough to listen to him.
God is able to do his work. He doesn’t need you, but he does need someone , and it may as well be you. Other people require the truth that you will acquire, assimilate, and disseminate. To the righteous, you can offer light and truth at a faster pace than they could acquire on their own. In far less time, you can convey what took you perhaps a lifetime to learn. To the unrighteous, you can offer—through your intercession—another opportunity for them to learn what they could have on their own if they were obedient and/or diligent.
Without the Lord’s condescending sacrifice, we could not obtain the light he offers us. To a much smaller but equally critical degree, your obtaining light depends on the condescension of others. You can’t be like the Lord without doing the things he did and does. You can, through your heed and diligence, obtain more than others. Then you can give it away through your condescension, supplying more to others than they were capable of obtaining by themselves. This is exactly what God did and does, and it is the whole purpose of creation. This is how you become a “savior on mount Zion” (see Obadiah 1:21).
You have a responsibility to obtain all the light you can, and to share it with others:
What I tell you in darkness, that speak ye in light: and what ye hear in the ear, that preach ye upon the housetops. (Matthew 10:27)
No man, when he hath lighted a candle, putteth it in a secret place, neither under a bushel, but on a candlestick, that they which come in may see the light. (Luke 11:33)
...it becometh every man who hath been warned to warn his neighbor. (D&C 88:81)
To the degree you do this, you will become a savior on mount Zion. To the extent that you do not, you will decrease the joy you have in this life and hereafter:
Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven. (Matthew 5:19)
When we are willing to share what we learn, the Lord gives us more:
For unto every one that hath shall be given, and he shall have abundance: but from him that hath not shall be taken away even that which he hath. (Matthew 25:29)
Those who are willing to share what they learn will find God giving them great treasures of specific wisdom just in time for them to share it with others who desperately need it.
If you don't also teach others what God has taught you, even perfect obedience to those instructions will not save you. If you do not obtain light and share it with others, you will be held responsible:
When I say unto the wicked, Thou shalt surely die; and thou givest him not warning, nor speakest to warn the wicked from his wicked way, to save his life; the same wicked man shall die in his iniquity; but his blood will I require at thine hand. (Ezekiel 3:18)
