Matthew 5:14-16 "Ye are the light of the world. A city that is set on an hill cannot be hid. 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. Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven."
Each of us a spiritual child of God, our loving Heavenly Father. He cares for us very much: "the worth of souls is great in the sight of God." (Doctrine and Covenants 18:10.) He cares for you very much. Because He loves each of us so deeply He asks that we be an example to the world so that more of His children can find Him and come back home.
I know that Heavenly Father gave us all unique gifts, talents, and personalities so that we can help each other find Christ. You have something unique, something that no one else has! Be bold. Don't be selfish; share youself! Be the best you that you can be! My mom has a poem on her fridge that says "Live so that those who know you, but don't know Him, will want to know Him, because they know you."
Be your best self for Christ! You owe it to Him.
