You should remember that you are literally and truly a son or daughter of Almighty God. You have been created in His very image.
He has sent you here to be successful and to have joy in your journey in mortality. He wants you to know that “with God nothing shall be impossible” (Luke 1:37). You are entitled through your worthiness to receive revelation to help you with your righteous endeavors. You may take upon you the name of the Lord. You may pray in His holy name. You can qualify to speak in the sacred name of God (see D&C 1:20). It matters not that times of tribulation will come. Your prayerful access to help is just as real as it was when David battled his Goliath.
So, to you I say, foster your faith. Fix your focus with an eye single to the glory of God. “Be strong and courageous” (2 Chronicles 32:7), and you will be given power and protection from on high. The Lord has declared His sustaining help: “For I will go before your face. I will be on your right hand and on your left, and my Spirit shall be in your hearts, and mine angels round about you, to bear you up” (D&C 84:88).
The Lord has more in mind for you than you have in mind for yourself! You have been reserved and preserved for this time and place. You can do hard things. At the same time, as you love Him and keep His commandments, great rewards—even unimaginable achievements—may be yours. Indeed, “eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him” (1 Corinthians 2:9).
You can accomplish the impossible. You can help shape the destiny of the entire human family! As you know and apply the teachings of the Lord in your lives and in your work, you can change the world.
