Moses feels inadequate when the Lord calls him. The Lord reassures Moses that He will be with him.
Exodus 3:11–12; 4:1, 10–12
11 And Moses said unto God, Who am I, that I should go unto Pharaoh, and that I should bring forth the children of Israel out of Egypt?
12 And he said, Certainly I will be with thee; and this shall be a token unto thee, that I have sent thee: When thou hast brought forth the people out of Egypt, ye shall serve God upon this mountain. . . .
1 And Moses answered and said, But, behold, they will not believe me, nor hearken unto my voice: for they will say, The Lord hath not appeared unto thee. . . .
10 And Moses said unto the Lord, O my Lord, I am not eloquent, neither heretofore, nor since thou hast spoken unto thy servant: but I am slow of speech, and of a slow tongue.
11 And the Lord said unto him, Who hath made man’s mouth? or who maketh the dumb, or deaf, or the seeing, or the blind? have not I the Lord?
12 Now therefore go, and I will be with thy mouth, and teach thee what thou shalt say.
President Gordon B. Hinckley said:
“It is not always easy to be obedient to the voice of the Lord. We may feel inadequate. I frequently draw comfort from the conversation Moses had with Jehovah, who called him to lead
Israel out of Egypt. Moses was a fugitive and a herder of sheep. How totally inadequate he must have felt!
“‘And Moses said unto the Lord, O my Lord, I am not eloquent . . . but I am slow of speech, and of a slow tongue.’ (And then I can almost hear him say, ‘Please don’t ask me.’)
“‘And the Lord said unto him, Who hath made man’s mouth? . . .
“‘Now therefore go, and I will be with thy mouth, and teach thee what thou shalt say’ (Exodus 4:10–12).”
