Jehovah appears to Abraham at Haran. All gospel blessings are promised to Abraham and his seed and through his seed to all the families and nations of the earth.
6 But I, Abraham, and Lot, my brother’s son, prayed unto the Lord, and the Lord appeared unto me, and said unto me: Arise, and take Lot with thee; for I have purposed to take thee away out of Haran, and to make of thee a minister to bear my name in a strange land which I will give unto thy seed after thee for an everlasting possession, when they hearken to my voice.
7 For I am the Lord thy God; I dwell in heaven; the earth is my footstool; I stretch my hand over the sea, and it obeys my voice; I cause the wind and the fire to be my chariot; I say to the mountains—Depart hence—and behold, they are taken away by a whirlwind, in an instant, suddenly.
8 My name is Jehovah, and I know the end from the beginning; therefore my hand shall be over thee.
9 And I will make of thee a great nation, and I will bless thee above measure, and make thy name great among all nations, and thou shalt be a blessing unto thy seed after thee, that in their hands they shall bear this ministry and Priesthood unto all nations;
10 And I will bless them through thy name; for as many as receive this Gospel shall be called after thy name, and shall be accounted thy seed, and shall rise up and bless thee, as their father;
11 And I will bless them that bless thee, and curse them that curse thee; and in thee (that is, in thy Priesthood) and in thy seed (that is, thy Priesthood), for I give unto thee a promise that this right shall continue in thee, and in thy seed after thee (that is to say, the literal seed, or the seed of the body) shall all the families of the earth be blessed, even with the blessings of the Gospel, which are the blessings of salvation, even of life eternal.
Elder David A. Bednar said:
“The heirs of all the promises and covenants made by God to Abraham are referred to as the seed of Abraham (see Bible Dictionary, ‘Seed of Abraham,’ 771). These blessings are obtained only by obedience to the laws and ordinances of the gospel of Jesus Christ. . . .
“Abraham was a great prophet who desired righteousness and was obedient to all of the commandments he received from God, including the command to offer as a sacrifice his precious son, Isaac. Because of his steadfastness and obedience, Abraham is often referred to as the father of the faithful, and Heavenly Father established a covenant with and promised great blessings to Abraham and his posterity . . .
“. . . Abraham was promised a great posterity and that the nations of the earth would be blessed through that posterity.
“How are the nations of the earth blessed through the seed of Abraham? The answer to this important question is found in the book of Abraham:
“‘And I will make of thee a great nation, and I will bless thee above measure, and make thy name great among all nations, and thou shalt be a blessing unto thy seed after thee, that in their hands they shall bear this ministry and Priesthood unto all nations;
“‘And I will bless them through thy name; for as many as receive this Gospel shall be called after thy name, and shall be accounted thy seed, and shall rise up and bless thee, as their father’ (Abraham 2:9–10).
“We learn in these verses that Abraham’s faithful heirs would have the blessings of the gospel of Jesus Christ and the authority of the priesthood. Thus, the phrase ‘bear this ministry and Priesthood unto all nations’ refers to the responsibility to proclaim the gospel of Jesus Christ and to invite all to receive by proper priesthood authority the ordinances of salvation. Truly, great responsibility rests upon the seed of Abraham in these latter days.
“How do these promises and blessings relate to us today? Either by literal lineage or adoption, . . . [w]e [Latter-day Saints] are the seed of Abraham. One of the primary reasons we receive a patriarchal blessing is to help us more fully understand who we are as the posterity of Abraham and to recognize the responsibility that rests upon us.
“. . . You and I, today and always, are to bless all peoples in all the nations of the earth. You and I, today and always, are to bear witness of Jesus Christ and declare the message of the Restoration. You and I, today and always, are to invite all to receive the ordinances of salvation.”
