Part 4 of The Church and the Restoration of Israel explores God's covenantal relationship with Israel and its theological and eschatological implications for the church. Central to this doctrine is the belief that Israel, as God's "firstborn son" (Amos 3:2), plays a unique and enduring role in God’s Kingdom plan. While the church and Israel have distinct roles, they are intertwined in God's redemptive narrative. The doctrine challenges Replacement Theology, affirming that Israel retains its prophetic destiny and is not replaced by the church. Historical milestones, such as the Zionist movement, the Balfour Declaration, and the reestablishment of Israel in 1948, are seen as fulfillments of biblical prophecy. Theologically, the church is called to provoke Israel to salvation (Romans 11:11) and partner in its physical and spiritual restoration (Isaiah 61:4-5). The final restoration of Israel includes the gathering of Jewish exiles from all nations (Isaiah 11:11-12) and the establishment of Christ’s Kingdom in Jerusalem (Micah 5:3). Ultimately, God’s covenant with Israel remains irrevocable, and the church is called to recognize and support His ongoing plan for Israel’s restoration and the unification of believing Jews and Gentiles in His eternal Kingdom.
