In order to answer that question, we need to go back, to the beginning, and see exactly what those promises were.

Promise #1:

God made a promise to Abraham in Genesis 12:2-3, he said, “...I will make of thee a great nation...I will bless them that bless thee and curse them that curse thee...in thee, all the families of the earth will be blessed.”

The first promise given to Abraham contained a prophecy of Jesus and also a millennial promise. This passage begins with a generalized prophecy concerning all of the physical descendants of Abraham and a future time of national greatness for those descendants. The promise speaks of a blessing and cursing to those who bless or curse Abraham and/or his descendants. It ends with a specific prophecy concerning the fact that all families of the earth will be blessed through the physical descendants of Abraham. The future (millennial) greatness of Abraham’s descendants will come about as a direct result of their acceptance of Christ as Messiah (Matthew 25: 31-46, Acts 3:25-26, Romans 11:12, Galatians 3:8).

Promise #2:
God goes on to promise Abraham in Genesis 13:15, “...For all the land which thou seest, to thee will I give it, and to thy seed forever.”

Abraham and his physical descendants are promised
physical possession of a physical geographical
location...forever.

Promise #3:
God says in Genesis 15:18, “...Unto thy seed have I given this land, from the river of Egypt unto the great river, the river Euphrates.”

Again we see a promise made to the physical descendants of Abraham concerning a specific
geographical location.

Promise #4:

Genesis 17:7-8 ...and I will establish my covenant between me and thee and thy seed after thee in their generations for an everlasting covenant, to be a God unto thee, and to thy seed after thee...and I will give unto thee, and to thy seed after thee, the land wherein thou art a stranger, all the land of Canaan, for an everlasting possession; and I will be their God.

In promising to be their God, we see a spiritual dimension added to the physical promises.

In addition to an everlasting covenant made
between Abraham and his physical descendants
concerning the geographic possession of all the
land of Canaan--there is also a promise made that his physical descendants will be the special people of God. They will ultimately allow their God to reign as King over them.

Promise #5:

Genesis 17:19 says, “...Sarah thy wife shall bear thee a son…and thou shall call his name Isaac...I will establish my covenant with him for an everlasting covenant, and with his seed...forever.”

The covenant promises to the descendants of Abraham are now narrowed to flow through the specific genealogy of his son, Isaac.

**Although Christians are referred to as the spiritual seed of Abraham, we are never referred to as the spiritual seed of Isaac. The physical descendants of Isaac are the Jewish people. They will inherit, literally, every promise made to Abraham concerning his posterity.

Abraham had many sons (Genesis 25:1-6), but only one through his wife Sarah, and it is through this son, Isaac, that all of the promises of God to Abraham were to be fulfilled.

Promise #6:

In Genesis 22:17-18, God promises, “...I will multiply thy seed as the sand of the seashore; and thy seed shall possess the gate of his enemies; and in thy seed shall all the families of the earth be blessed…”

Again, Abraham is promised many physical descendants, and both messianic and millennial promises are given. Abraham’s descendants are promised victory over their enemies. This also corresponds with Romans 11:12.

Promise #7:

Genesis 26:3-4 says (to Isaac), “...Unto thee, and unto thy seed, I will give all these countries...and in thy seed shall all the nations of the earth be blessed….”

The reference to the nations identifies this as a millennial blessing that will be bestowed on the nations. And again, the promise to Abraham is passed on to his son, Isaac. Isaac is told that his physical descendants will possess all the land of Canaan...He is promised that all nations of the earth (those not of Jewish descent) will be blessed by his physical descendants—one physical descendent in particular—Jesus (Acts 3:25-26, Romans 11:12, Galatians 3:8).

Promise #8:

Genesis 27:28-29 records Isaac passing the promise to Jacob, “...let people serve thee, and nations bow down
to thee: Be lord over thy brethren, and let thy mother’s son’s bow down to thee: cursed be everyone that curses thee, and blessed be he that blesses thee.”

The land and [millennial] leadership Covenant is passed from Isaac to Jacob (many times, we see the physical descendants of Abraham, the Jewish people, referred to as “Jacob” in scripture. The spiritual seed of Abraham—the Israel of God—the Church—Is never referred to as Jacob).

Promise #9:

Genesis 28:13-14 says, “...The land whereon thou liest, to thee will I give it, and to thy seed; ...and in thee and in thy seed, shall all the families of the earth be blessed...”

God confirms the land covenant and the messianic and millennial blessing with Jacob. Jacob’s physical descendants will inherit the geographical location of Canaan, and in Jacob’s seed all families of the earth will be blessed (Acts 3:25-26, Romans 11:12, Galatians 3:8).

Promise #10:

Genesis 35:10-12 says, “...thy name shall no longer be called Jacob, but Israel shall be thy name...and the land which I gave Abraham and Isaac, to thee will I give it, and to thy seed after thee...”

God changes Jacob’s name to Israel and reaffirms that his physical descendants will inherit a physical geographic location.

God’s covenant with Abraham was not only a messianic promise, but also a millennial promise. Abraham’s physical descendants will inherit a physical geographic location, they will prevail over all their enemies, they will rule, and they will be a blessing to all—that means every one of—the families of the earth.

We know that all of these promises are rooted in the greatest blessing we have received thus far from the descendants of Abraham—the son of David, Jesus Christ, the Messiah, who died for the sins of the whole world.

But there is yet another blessing in store for all the “nations” and “families” of the earth. Through Jesus Christ, God will use the physical descendants of Abraham to be a blessing to every family of the millennial earth (Isaiah 65:8, Zechariah 8:13, Romans 11:11-12,15).

Every one of the above mentioned promises to Abraham will be fulfilled through his natural seed (those descended from Isaac and Jacob)—The promises will be fulfilled in those who survive the time of Jacob’s Trouble, the Judgment of the Nations, and enter the Kingdom of Christ in their physical, mortal, condition.
