What does it mean to be the seed of Abraham? Scripturally it has a deeper meaning than being his literal descendants. The Lord made a covenant with Abraham, the great patriarch, that all nations would be blessed through him. Any man or woman can claim the blessings of Abraham. They become his seed and heirs to the promised blessings by accepting the gospel, being baptized, entering into temple marriage, being faithful in keeping their covenants, and helping to carry the gospel to all the nations of the earth.
I want to say to you, read the book, the Pearl of Great Price, and read the Book of Abraham. The Pearl of Great Price I hold to be one of the most intelligent, one of the most religious books that the world has ever had; but more than that, to me the Pearl of Great Price is true in its name. It contains an ideal of life that is higher and grander and more glorious than I think is found in the pages of any other book unless it be the Holy Bible. It behooves us to read these things, understand them: and I thank God when they are attacked, because it brings to me, after a study and thought, back to the fact that what God has given He has given, and He has nothing to retract." - Levi Edgar Young, Conference Report (April 1913), 74
"...it must be evident to all who seriously consider the matter, that if the Book of Abraham as given to us by Joseph Smith be true, it must have been translated by a greater than human power." - George Reynolds, The Book of Abraham: Its Authenticity Established as a Divine and Ancient Record (Salt Lake City: Deseret News, 1879), 4
