Jehovah (who is the premortal Jesus Christ and God of the Old Testament) appears to Moses and talks with him face to face. Moses learns that he is a son of God (Heavenly Father) in the similitude of the Only Begotten of the Father (Jesus Christ).

Moses 1:1–11

1 The words of God, which he spake unto Moses at a time when Moses was caught up into an exceedingly high mountain,
2 And he saw God face to face, and he talked with him, and the glory of God was upon Moses; therefore Moses could endure his presence.
3 And God spake unto Moses, saying: Behold, I am the Lord God Almighty, and Endless is my name; for I am without beginning of days or end of years; and is not this endless?
4 And, behold, thou art my son; wherefore look, and I will show thee the workmanship of mine hands; but not all, for my works are without end, and also my words, for they never cease.
5 Wherefore, no man can behold all my works, except he behold all my glory; and no man can behold all my glory, and afterwards remain in the flesh on the earth.
6 And I have a work for thee, Moses, my son; and thou art in the similitude of mine Only Begotten; and mine Only Begotten is and shall be the Savior, for he is full of grace and truth; but there is no God beside me, and all things are present with me, for I know them all.
7 And now, behold, this one thing I show unto thee, Moses, my son, for thou art in the world, and now I show it unto thee.
8 And it came to pass that Moses looked, and beheld the world upon which he was created; and Moses beheld the world and the ends thereof, and all the children of men which are, and which were created; of the same he greatly marveled and wondered.
9 And the presence of God withdrew from Moses, that his glory was not upon Moses; and Moses was left unto himself. And as he was left unto himself, he fell unto the earth.
10 And it came to pass that it was for the space of many hours before Moses did again receive his natural strength like unto man; and he said unto himself: Now, for this cause I know that man is nothing, which thing I never had supposed.
11 But now mine own eyes have beheld God; but not my natural, but my spiritual eyes, for my natural eyes could not have beheld; for I should have withered and died in his presence; but his glory was upon me; and I beheld his face, for I was transfigured before him.

President Dallin H. Oaks said:

“Consider the power of the idea taught in our beloved song ‘I Am a Child of God.’ . . . Here is the answer to one of life’s great questions, ‘Who am I?’ I am a child of God with a spirit lineage to heavenly parents. That parentage defines our eternal potential. That powerful idea is a potent antidepressant. It can strengthen each of us to make righteous choices and to seek the best that is within us. Establish in the mind of a . . . person the powerful idea that he or she is a child of God, and you have given self-respect and motivation to move against the problems of life.”
