2 Nephi 22:2-3

2. Behold, God is my salvation; I will trust, and not be afraid; for the Lord JEHOVAH is my strength and my song; he also has become my salvation.
3. Therefore, with joy shall ye draw water out of the wells of salvation.

1 Nephi 8:12/24-25

12 And as I partook of the fruit thereof it filled my soul with exceedingly great joy; wherefore, I began to be desirous that my family should partake of it also; for I knew that it was desirable above all other fruit.

24. And it came to pass that I beheld others pressing forward, and they came forth and caught hold of the end of the rod of iron; and they did press forward through the mist of darkness, clinging to the rod of iron, even until they did come forth and partake of the fruit of the tree.
25. And after they had partaken of the fruit of the tree they did cast their eyes about as if they were ashamed.

1 Nephi 3:31-4:1

31. And after the angel had departed, Laman and Lemuel again began to murmur, saying: How is it possible that the Lord will deliver Laban into our hands? Behold, he is a mighty man, and he can command fifty, yea, even he can slay fifty; then why not us?
1. And it came to pass that I spake unto my brethren, saying: Let us go up again unto Jerusalem, and let us be faithful in keeping the commandments of the Lord; for behold he is mightier than all the earth, then why not mightier than Laban and his fifty, yea, or even than his tens of thousands?

The overwhelming feeling that I have in receiving this call is that we must live by faith and not by fear.

2 Timothy 1:7

7. For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind.

D&C 6:33-34

33. Fear not to do good, my sons, for whatsoever you sow, that shall ye also reap; therefore, if ye sow good ye shall also reap good for your reward.
34. Therefore, fear not, little flock; do good; let earth and hell combine against you, for if ye are built upon my rock, they cannot prevail.
