The Centrality of a Nation

To understand the narrative of Scripture is to understand the story of a people. From the early chapters of Genesis to the final pages of Revelation, the redemptive plan of God unfolds in real time, on a geographical stage, through a chosen lineage. That lineage is the nation of Israel. Without Israel, the covenants lose their context, the prophecies lose their target, and the coming of the Messiah loses its historical anchor. The promises to David about an eternal throne make no sense without the nation he ruled. The prophecies of Isaiah and Jeremiah concerning a New Covenant are directed first to the “house of Israel and with the house of Judah” (Jeremiah 31:31).

Israel was the nation God chose to entrust with His word, the people through whom He would reveal His character, and the lineage from which He would bring forth a blessing for the world. The Apostle Paul affirms that to the Israelites “belongs the adoption as sons, and the glory and the covenants and the giving of the Law and the temple service and the promises” (Romans 9:4). The covenants God made, beginning with Abraham, were not just promises to individuals; they were the documents that established and governed this nation. Therefore, to trace the story of redemption is to trace the history of Israel, from its birth from an elderly, childless couple to its role as the heritage of the messiah. Understanding this relationship is essential for grasping how God’s promises to this one nation led to a salvation offered to all nations.

The Call of Abraham: A New Beginning

The story begins with Abraham. After God scatters the nations at the Tower of Babel, the focus shifts to God’s dealings with one man to initiate a plan of redemption. For reasons rooted in His will, God called Abram (later renamed Abraham) from the city of Ur of the Chaldees. This was a centre of Mesopotamian civilisation, known for its culture and its devotion to the moon god, Nanna. Joshua 24:2 confirms that Abraham’s family, including his father Terah, “served other gods.” This context is important: God did not call a righteous man from a righteous lineage. He chose an elderly, childless man from an idolatrous family and his barren wife, Sarai (later named Sarah). By selecting the weak and the old, God ensured from the outset that the fulfilment of His promise could not be attributed to human merit, but only to His power.

It was to this pair that God made a promise that would redirect human history. This promise, often called the Abrahamic Covenant, contains seven “I will” statements from God: “Now the LORD said to Abram, ‘Go forth from your country, And from your relatives And from your father’s house, To the land which I will show you; And I will make you a great nation, And I will bless you, And make your name great; And so you shall be a blessing; And I will bless those who bless you, And the one who curses you I will curse. And in you all the families of the earth will be blessed’” (Genesis 12:1-3). This call was a demand for faith. It required Abraham to abandon every source of security—his national identity (“your country”), his kinship circle (“your relatives”), and his household (“your father’s house”)—and to journey to a land based solely on the word of a God he was just beginning to know. His obedience was the first step in a journey that would define salvation history.

Abraham, the Friend of God

The relationship between God and Abraham was unparalleled, established not between equals but as an act of grace. Abraham, a man from a pagan background, could offer nothing to God. Yet God, in His sovereignty, initiated a covenant with him and engaged with him as one would a friend. This relationship began with Abraham’s fear before the divine. When God first revealed the covenant through a vision, a “terror and great darkness fell upon him” (Genesis 15:12). This foundation of reverence gave rise to a tension that defined their interactions. On one hand, Abraham approached God with confidence, as seen when he interceded for Sodom and Gomorrah, negotiating with the Almighty (Genesis 18:22-33). On the other hand, his fear and reverence were evident throughout his walk with God. When God appeared to him to establish the covenant of circumcision, Abraham’s immediate response was to fall on his face in worship (Genesis 17:3). Even in his confident intercession for Sodom, he prefaced his pleas with humility, acknowledging, “Now behold, I have ventured to speak to the Lord, although I am but dust and ashes” (Genesis 18:27). This reverence culminated in his ultimate act of obedience: the willingness to offer Isaac, his son of promise, demonstrating a fear of God that superseded even his love for his child.

This title, “the friend of God” (Isaiah 41:8; James 2:23), was never the foundation of their relationship, but its consequence. It was a status God bestowed upon him. The Scripture states, “Abraham believed God, and it was credited to him as righteousness” (Romans 4:3). It was after God declared him righteous through faith that He began to commune with him with such intimacy, bringing him into His divine counsel. Friendship with God was the result of a relationship that began with a holy fear and was sustained by a faith that God Himself honoured.

The Unconditional Promise

The covenant God made with Abraham was unveiled in stages. It was formalised and repeated on several occasions, with each instance adding depth and clarity to the original promise. This was a promise from the Creator to a creature, with its terms dictated by God’s grace. In the ancient world, there were two main types of treaties: the suzerain-vassal treaty, where a king imposed obligations on a vassal, and the royal grant, where a king bestowed a gift upon a subject. The Abrahamic Covenant is a royal grant. The covenant was ratified by God Himself, who took the burden of its fulfilment upon His own faithfulness. This promise consisted of three components that would define redemption: the gift of a land, the creation of a people (or seed), and the extension of a blessing that would flow from that people to the rest of the world.

The Land

The promise of a territory was central to the covenant. This was formalised in a ceremony described in Genesis 15. God commanded Abram to prepare sacrificed animals, cutting them in half. In the ancient Near East, this was a self-maledictory oath; the two parties would walk between the pieces, signifying, “May it be done to me as was done to these animals if I break this covenant.” Yet, in a display of grace, Abram was put into a deep sleep. A smoking oven and a flaming torch, symbolising the presence of God, passed between the pieces alone. This act signified that God was taking the weight of the covenant’s obligations upon Himself, including the penalty for failure. It was an unconditional promise, dependent solely on God’s faithfulness. “On that day the LORD made a covenant with Abram, saying, ‘To your descendants I have given this land, From the river of Egypt as far as the great river, the river Euphrates’” (Genesis 15:18). This land was to be a stage for redemptive history, a place where God would dwell with His people.

The People (Seed)

Years later, with the promise still unfulfilled and Abraham now ninety-nine years old, God reaffirmed His covenant. He changed Abram’s name (“exalted father”) to Abraham (“father of a multitude”), and Sarai’s (“my princess”) to Sarah (“princess to many”), signifying their destiny as progenitors of nations and kings. God declared, “I will establish My covenant between Me and you and your descendants after you throughout their generations for an everlasting covenant, to be God to you and to your descendants after you… I will make you exceedingly fruitful, and I will make nations of you, and kings will come forth from you” (Genesis 17:6-7). This promise of descendants was a miracle, given Abraham’s age and Sarah’s barrenness. The sign of this covenant was circumcision, a mark in the flesh identifying Abraham’s descendants as the people of the promise. It served as a reminder that fruitfulness and their existence as a nation came not from natural ability but from God’s power.

The Covenant Lineage: From Abraham to the Twelve Tribes

The promise to make Abraham a “great nation” unfolded over generations, marked by God’s selection of the covenant heir at each stage. This process demonstrates that the covenant lineage was not determined by human customs, such as primogeniture, but by divine election. Abraham’s first son was Ishmael, born through Sarah’s maidservant Hagar. While God promised to bless Ishmael and make him a nation, the covenant of promise was passed to Isaac, the son born to Abraham and Sarah in their old age. God’s word was clear: “through Isaac your descendants shall be named” (Genesis 21:12).

This pattern of choice over natural order continued into the next generation. Isaac and Rebekah had twin sons, Esau and Jacob. By right of birth, the blessing belonged to Esau, the elder. However, God had declared even before their birth, “The older shall serve the younger” (Genesis 25:23), a choice Paul later cites to illustrate that God’s purpose stands “not because of works but because of Him who calls” (Romans 9:11-12). Through events involving human planning and providence, Jacob received the birthright and the blessing, securing his place as the next patriarch in the covenant line.

Jacob’s life culminated in him being renamed “Israel” by God after he wrestled with a divine being (Genesis 32:28). He then fathered twelve sons—Reuben, Simeon, Levi, Judah, Dan, Naphtali, Gad, Asher, Issachar, Zebulun, Joseph, and Benjamin. These sons became the progenitors of the twelve tribes that would form the nation of Israel. The family grew into a clan, and during their time in Egypt, they multiplied into a nation. Their exodus from Egypt and receiving of the Law at Mount Sinai marked their establishment as the nation of Israel, the people God had promised to Abraham centuries earlier. It was through this chosen lineage that the promise of a “great nation” journeyed toward its fulfilment.

The Universal Blessing & The Offering of Isaac: A Divine Foreshadowing

The scope of the covenant was revealed after Abraham demonstrated his faith in the test of offering his son, Isaac, on Mount Moriah. Because Abraham did not withhold his son, God reconfirmed His promise with an oath. He swore by Himself, saying, “indeed I will greatly bless you, and I will greatly multiply your seed as the stars of the heavens and as the sand which is on the seashore… In your seed all the nations of the earth shall be blessed, because you have obeyed My voice” (Genesis 22:17-18).

This account is one of the types of Christ in the Old Testament. This act of faith became the basis for extending the blessing beyond Israel, serving as a foreshadowing of the Father’s offering of His own Son:

• The Beloved Son: God commands Abraham, “Take now your son, your only son, whom you love, Isaac” (Genesis 22:2), language that echoes God the Father’s declaration concerning Jesus, “This is My beloved Son, in whom I am well-pleased” (Matthew 3:17).
• The Journey and the Wood: Isaac submits to his father’s will and carries the wood for his own sacrifice up the mountain, a parallel to Jesus carrying His own cross to Golgotha, which took place in the same vicinity.
• A Divine Provision: Just as Abraham declared, “God will provide for Himself the lamb,” God provided a ram caught in the thicket as a substitute for Isaac. This points to Jesus as the “Behold, the Lamb of God who takes away the sin of the world!” (John 1:29).
• Resurrection Hope: The book of Hebrews reveals Abraham’s faith: “He considered that God is able to raise people even from the dead, from which he also received him back as a type” (Hebrews 11:19). Abraham’s three-day journey culminated in receiving his son back from the brink of death, a foreshadowing of Christ’s resurrection on the third day.

This covenant was unconditional in its fulfilment and eternal in duration. Unlike the later Mosaic Covenant, its promises did not depend on Israel’s obedience but on God’s faithfulness. This covenant established the lineage and the nation through which God would bring the Messiah and His salvation to the world.

The Singular Seed: The Messianic Fulfilment

The final aspect of the Abrahamic Covenant is the promise that “in your seed all the nations of the earth shall be blessed.” The word “seed” in Hebrew (zera) can be used in both a singular and a collective sense. It can refer to a multitude of descendants, like the stars of heaven, but it can also refer to a single descendant. The Apostle Paul, under the inspiration of the Holy Spirit, clarifies the meaning of this promise.

“Now the promises were spoken to Abraham and to his seed. He does not say, ‘And to seeds,’ as one would in referring to many, but rather as in referring to one, ‘And to your seed,’ that is, Christ” (Galatians 3:16).

Christ is the ultimate Seed of Abraham. He is the fulfilment of the promise. It is through Him that the blessing of forgiveness and reconciliation with God extends to all nations. The Abrahamic, Mosaic, and Davidic covenants all converge on His person and work. He is the true Israel, the descendant who fulfilled the covenant obligations. This covenant with Abraham is where God begins to narrow the focus of His redemptive plan, setting the historical stage for the Messiah’s arrival. By understanding this, we can view Jesus as the fulfilment of a promise made thousands of years earlier to a man from Ur. He is the reason Abraham was called, the reason Israel was chosen, and the blessing for all nations. He is God’s answer to His own unconditional promise.

Abraham: Father of the Faithful

The New Testament makes it clear that Abraham’s significance lies not just in his physical lineage, but in his spiritual fatherhood over all who believe. The Apostle Paul, in Romans 4, argues that Abraham is the prototype of a person justified by faith. He establishes that “ABRAHAM BELIEVED GOD, AND IT WAS CREDITED TO HIM AS RIGHTEOUSNESS” (Romans 4:3) long before he received the sign of circumcision. This timing is important. Paul explains that Abraham “received the sign of circumcision, a seal of the righteousness of the faith which he had while uncircumcised, so that he might be the father of all who believe without being circumcised, that righteousness might be credited to them” (Romans 4:11).

By this, God established him as the father of two groups of people:

1. The Father of the circumcised (Jews) who not only are circumcised but who also walk in the steps of the faith of their father Abraham.
2. The Father of all who believe without being circumcised (Gentiles), so that righteousness might be credited to them.

Therefore, the children of Abraham are not defined by bloodline or ritual, but by a shared faith. This concept broke down the dividing wall between Jew and Gentile. As Paul writes, “For this reason it is by faith, in order that it may be in accordance with grace, so that the promise will be guaranteed to all the descendants, not only to those who are of the Law, but also to those who are of the faith of Abraham, who is the father of us all” (Romans 4:16). This principle unites Jewish and Gentile believers into one family, making them all heirs to the blessing promised to Abraham.

The Enduring Relevance of Israel: The Olive Tree

The unconditional nature of the Abrahamic Covenant has implications for how we understand Israel’s place in God’s plan today. A common view is that the Church has replaced Israel as God’s covenant people (a view called Replacement Theology or Supersessionism). This perspective suggests that because Israel as a nation rejected their Messiah, God has transferred the covenant promises made to them exclusively to the Christian Church. The New Testament presents a different picture. The Apostle Paul, defending God’s faithfulness in his letter to the Romans, addresses this issue in chapters 9 through 11.

Using the metaphor of an olive tree, Paul explains the relationship between ethnic Israel and Gentile believers. The tree’s root is holy, representing the patriarchs (Abraham, Isaac, and Jacob) and the covenant promises God made to them. The natural branches are the people of Israel, the descendants of Abraham. Paul explains that because of unbelief in their Messiah, some of these natural branches were broken off. In their place, Gentile believers, who were branches from a “wild olive,” have been “grafted in among them and became a partaker with them of the rich root of the olive tree” (Romans 11:17). This imagery makes several points that dismantle the idea of replacement theology:

• Gentiles are Joined, Not Substituted. Paul’s language is one of addition, not substitution. The Church does not replace Israel; rather, Gentile believers are brought into the covenant community, which has always been defined by faith. They draw life from the same “root of promise”—the Abrahamic Covenant—that sustained the faithful remnant of Israel. This shows that God’s redemptive plan is a single story, not two separate plans. As Paul states elsewhere, “if you belong to Christ, then you are Abraham’s descendants, heirs according to promise” (Galatians 3:29).
• The Root of Promise Supports the Church. The metaphor establishes the source of spiritual life. The root—representing God’s unconditional promises to the patriarchs—is what nourishes and sustains all the branches, both natural (Jewish believers) and grafted-in (Gentile believers). It is not the Church that supports the promises, but the promises that support the Church. This is a rebuke to any form of Gentile arrogance.
• Faith is the Condition for Remaining. The reason some natural branches were broken off was “unbelief.” The reason the wild branches were grafted in was “faith.” Paul uses this to issue a warning to Gentile believers: “Do not be conceited, but fear; for if God did not spare the natural branches, He will not spare you, either” (Romans 11:20-21). This establishes a principle: one’s connection to the tree of God’s covenant people is maintained by faith, not by ethnicity.
• Israel’s Future Restoration is Guaranteed. Paul’s argument culminates in a refutation of the idea that God is finished with ethnic Israel. He reveals a “mystery” to prevent Gentile believers from becoming “wise in their own estimation.” He explains that Israel’s current “partial hardening” is temporary and serves a redemptive purpose: to allow the “fullness of the Gentiles” to come in. After this period, the natural branches will be grafted back into “their own olive tree” (Romans 11:24). This will culminate in a future salvation of the nation, as Paul concludes, “and so all Israel will be saved” (Romans 11:26). This future restoration is the proof of God’s faithfulness to the unconditional promises He made to Abraham.
