For this topic see: Genesis 12:1-3; 13:14-17; 15:1-5; JST, Genesis 17:1-2; Abraham 2:8-11
“And it was in the night time when the Lord spake these words unto me: I will multiply thee, and thy seed after thee, like unto these [stars]; and if thou canst count the number of sands, so shall be the number of thy seeds.” – Abraham 3:14
What, then, is the Abrahamic covenant? It is that Abraham and his seed (including those adopted into his family) shall have all of the blessings of the gospel, of the priesthood, and of eternal life. The gate to eternal life is celestial marriage, which holy order of matrimony enables the family unit to continue in eternity, so that the participating parties may have posterity as numerous as the sands upon the seashore or the stars in heaven. The Abrahamic covenant enables men to create for themselves eternal family units that are patterned after the family of God our Heavenly Father. A lesser part of the covenant is that the seed of Abraham have the Millennial destiny of inheriting as an everlasting possession the very land of Canaan whereon the feet of the righteous have trod in days gone by. – Elder Bruce R. McConkie, A New Witness for the Articles of Faith, 503–5; Pearl of Great Price Student Manual, p. 34
Being an heir to the Abrahamic covenant does not make one a “chosen person” per se, but does signify that such are chosen to responsibly carry the gospel to all the peoples of the earth. Abraham’s seed have carried out the missionary activity in all the nations since Abraham’s day. – Matt. 3:9; Abr. 2:9–11; Bible Dictionary, “Abraham, Covenant of,” 602.
The responsibility of the seed of Abraham, which we are, is to be missionaries to ‘bear this ministry and Priesthood unto all nations’ (Abraham 2:9). – President Ezra Taft Benson, Conference Report, Apr. 1987, p. 107; or Ensign, May 1987, p. 85
The same keys of the priesthood given to Abraham have been restored to the earth in the latter days. On 3 April 1836 a prophet named Elias appeared to Joseph Smith and Oliver Cowdery in the newly dedicated Kirtland Temple and committed to them “the gospel of Abraham, saying that in us and our seed all generations after us should be blessed” (D&C 110:12). With these keys of the priesthood on earth once again, a person can receive all of the blessings given to Abraham (see D&C 132:29–33). – Pearl of Great Price Student Manual, p. 34
When the Lord called Abraham out of Ur, the land of his fathers, he made certain covenants with him because of his faithfulness. One promise was that through him and his seed after him all nations of the earth should be blessed. This blessing is accomplished in several ways.
1. Through Jesus Christ who came through the lineage of Abraham;
2. Through the priesthood which was conferred upon Abraham and his descendants;
3. Through the scattering of Israel among all nations by which the blood of Israel was sprinkled among the nations, and thus the nations partake of the leaven of righteousness, on condition of their repentance, and are entitled to the promises made to the children of Abraham; and
4. In the fact that the Lord covenanted with Abraham that after his time all who embraced the gospel should be called by his name, or, should be numbered among his seed, and should receive the Holy Ghost. – Pres. Joseph Fielding Smith, Doctrines of Salvation, 3:246-247
