You may ask what can I do? How can I make a difference in the world? You have something that no one can take away that is the light that comes from your countenance and your eyes that no matter how dark and evil the world may come you can spread light. “And the Spirit giveth light to every man that cometh into the world; and the Spirit enlighteneth every man through the world, that hearkeneth to the voice of the Spirit.” (D&C 84:45–46.) Matthew 5:14-16
14 Ye are the light of the world. A city that is set on an hill cannot be hid.
15 Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house.
16 Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.
Ether 6:3 “And thus the Lord caused stones to shine in darkness, to give light unto men, women, and children, that they might not cross the great waters in darkness.”
