The Tanakh (Hebrew Bible) clearly presents the basis for God’s choice of Israel as His covenant nation. This selection was not based on Israel’s inherent greatness or merit but entirely on God’s love, promise, and covenant faithfulness.
A central passage explaining this appears in Deuteronomy 7:6–8:
“For you are a people holy to the LORD your God. The LORD your God has chosen you out of all the peoples on the face of the earth to be his people, his treasured possession. The LORD did not set his affection on you and choose you because you were more numerous than other peoples, for you were the fewest of all peoples. But it was because the LORD loved you and kept the oath he swore to your ancestors…”
From this, two core reasons emerge:
- Divine Love and Grace – God chose Israel not because of their power or size, but out of His sovereign love and favor.
- Faithfulness to Covenant Promises – God’s choice fulfilled His oath to Abraham, Isaac, and Jacob (Genesis 12:1–3; 15:18; 17:7–8), showcasing His unchanging commitment to His word.
God’s purpose for choosing Israel was not merely for privilege, but for mission. According to Exodus 19:5–6, Israel was to be a “kingdom of priests and a holy nation”—a mediating people who would reveal God to the nations. Isaiah adds that Israel was to be “a light to the Gentiles” (Isaiah 42:6; 49:6), bringing salvation to the ends of the earth.
However, under the Mosaic Covenant, Israel repeatedly failed in its God-given mission. Their disobedience, idolatry, and rejection of God’s ways culminated in exile, temple destruction, and spiritual separation with no means of atonement under the Law. Because of Israel’s persistent failure to uphold the Mosaic Covenant, a new and more perfect covenant became necessary—a covenant written on hearts rather than tablets of stone (Jeremiah 31:31–34).
This New Covenant finds its fulfillment in Jesus the Messiah, the one chosen by God who perfectly embodied the role and calling originally given to Israel:
- He demonstrated complete obedience to God’s law (Matthew 5:17–18).
- He acted as the ultimate High Priest and mediator (Hebrews 4:14–16).
- He fulfilled the prophetic vision of being a light to the Gentiles (Isaiah 49:6; Luke 2:32; John 8:12).
Jesus not only fulfilled the moral and spiritual calling of Israel, He also fulfilled the covenant promises given to the patriarchs:
- He is the promised “seed” of Abraham through whom all nations are blessed (Genesis 12:3; Galatians 3:16).
- His death and resurrection inaugurated the New Covenant, replacing the Mosaic Covenant and its annual sacrificial system in the Temple as the basis for God’s redemptive work in the world (Luke 22:20; Hebrews 8:6–13).
- Jesus the promised seed of Abraham relived and redeemed Israel’s story—His 40 days of temptation in the wilderness mirrored Israel’s 40 years, yet He succeeded where they failed (Matthew 4:1–11).
Through His once-for-all-time atoning sacrifice, Jesus created a new covenant community composed of Jews and Gentiles alike—united by faith, not by ethnicity or law. As Paul writes:
“There is neither Jew nor Greek… for you are all one in Christ Jesus” (Galatians 3:28).
- Gentiles are grafted into the covenant promises (Romans 11:17–24).
- The dividing wall between Jew and Gentile has been broken down (Ephesians 2:11–22).
In this new reality, the Church becomes the instrument of God’s redemptive mission. While ethnic Israel was the chosen vehicle for achieving redemption under the Mosaic Covenant, the universal Church—composed of all individuals who have accepted Jesus as their Lord and Savior—now fulfills the role of God’s holy nation and kingdom of priests (1 Peter 2:9–10). This new system, based on the sacrifice of Jesus and foreshadowed by Abraham offering his son Isaac as an act of faith, does not merely expand upon the Mosaic Covenant; rather, it fulfills and supersedes it, establishing a more perfect and enduring relationship between God and humanity.
But, it is important to note as Paul clarifies, God has not rejected ethnic Israel entirely. Only its role as God’s instrument for revealing his redemptive plan to the world has changed (Romans 11:25–29). The promise of a land and peoplehood in perpetuity made to the patriarchs is still in effect for the Jewish people.
Jesus declared that the kingdom of God had arrived through His ministry (Mark 1:14–15), and the New Covenant confirms that the eternal kingdom foreseen by the prophets is now being built through Him (Daniel 7:13–14; Revelation 21–22). The Church is not an afterthought—it is the true fulfillment of God’s redemptive plan that began with Abraham and was advanced through Israel, now realized in Jesus and extended to the nations.
