Many Christians today are taught to separate Israel and the Church — as if God has two different plans, two sets of promises, and two peoples. But Paul’s letters push in the opposite direction. For Paul, there was always one plan of God, rooted in Abraham’s promises and fulfilled in Christ.
The Heart of the Dispensational Claim
Dispensationalism often says:
- Israel = earthly promises (land, nation, kings).
- Church = spiritual promises (heaven, Spirit, forgiveness).
This view implies God’s promises to Abraham still await a separate, future fulfillment for ethnic Israel apart from the church.
But Paul doesn’t let us draw those lines.
Paul’s Vision: One People of God
In Galatians 3, Paul makes a radical claim:
- “If you are Christ’s, then you are Abraham’s offspring, heirs according to promise” (Gal. 3:29).
- Jew and Gentile are united into one family (Gal. 3:28).
- The inheritance is shared: “heir of the world” (Rom. 4:13).
In other words, Abraham’s promises weren’t split into two tracks (Israel vs. Church). They were always designed to converge in Christ — and all who believe in Him are heirs. He asserts that the crucial factor for belonging to God’s people is not adherence to the law or physical lineage, but rather being a new creation in Christ. By saying “and upon the Israel of God,” Paul signifies that all believers—both Jews and Gentiles united in faith—are now considered the true Israel.
This idea is further elaborated in discussions about how Gentiles are not merely added to physical Israel but are incorporated into something entirely new—the body of Christ. Paul later says in Rom 9:6-8
For they are not all Israel who are descended from Israel; nor are they all children because they are Abraham’s descendants, but: “through Isaac your descendants will be named.” That is, it is not the children of the flesh who are children of God, but the children of the promise are regarded as descendants.
Rereading the Abrahamic Promises in Christ
Let’s connect the dots the way Paul does:
- Land → Expanded in Christ to the whole world (Rom. 4:13).
- Nationhood → Redefined as a worldwide family of faith (Gal. 3:7, 29).
- Blessing → Justification and the Spirit given to Jew and Gentile alike (Gal. 3:8, 14).
- Kingship → Christ as the universal King (Rom. 1:3; 1 Tim. 6:15).
- Covenant/Righteousness → Secured by faith, not law (Rom. 4:3; Gal. 3:6).
Every strand funnels into one plan in Christ — and is distributed to all believers, Jew or Gentile, who share Abraham’s faith.
Why This Matters
- It safeguards God’s faithfulness. If God had “two plans,” one for Israel and another for the Church, then His promises would be divided. But Paul shows that God had one purpose from the start: “that in you all nations shall be blessed” (Gen. 12:3).
- It shapes our identity. The Church is not a “parenthesis” in God’s plan — it is the fulfillment of the Abrahamic promise, the true people of God.
- It reorients our hope. We aren’t waiting for a separate earthly kingdom for Israel. We await the renewal of all creation (Rom. 8:21), where Abraham’s global inheritance is shared by the one family of faith.
Paul’s Slap-in-the-Face Moment
In Romans 4, Paul even flips expectations: Abraham was credited righteousness before circumcision — meaning Gentiles who believe are in on the promise, while circumcised Jews only share it if they also walk in Abraham’s faith (Rom. 4:11–12).
This was shocking in Paul’s day, and it still challenges us: the dividing line is not circumcision, not ethnicity, not Torah — it is Christ.
Conclusion: One Unified Plan
From Genesis to Galatians, from Abraham to Christ, God has one covenant family. The promises of land, nationhood, blessing, kingship, and righteousness are not split between Israel and the Church. They all converge in Christ, and they all belong to those who believe.
So when Paul says in Galatians 6:16, “peace and mercy be upon…the Israel of God,” he isn’t creating a new category. He’s naming what the church already is: the true continuation of Abraham’s family, Jew and Gentile together in Christ.
