Galations 3

 Paul explained -  

"...if ye be Christ’s, then are ye Abraham’s seed, and heirs according to the promise."  (Galatians 3:29)

Which suggests that if we are obedient and enter into and keep the law, ordinances, and covenants of the plan of salvation, we become Abraham's seed and entitled to all his blessings.  Which would be same for the lineage of Isaac, Jacob (Israel), and the tribes of Israel.  The promises of Abraham include:

1. Abraham’s posterity will be numerous, even innumerable (Doctrine and Covenants 132:30)

2. Abraham will be blessed to receive and live in a promised land (Abraham 2:6,19)

3. All the nations of the earth will be blessed through the seed of Abraham (Abraham 2:11)

4. Abraham’s seed would bear the ministry of the gospel and the priesthood to all nations, sharing the blessings of the gospel, which are the blessings of salvation, even of life eternal (Abraham 2:9-11)

5.Abraham received the priesthood (Doctrine and Covenants 84:14), and he was promised that his posterity would have the right to the Priesthood.
