Your system creates an unbiblical segregation in the family of God, where Christ has two brides, two peoples, and two separate inheritances.
But the New Testament logic is an unyielding unit:
- Christ is the singular Seed of Abraham (Galatians 3:16).
- Christ is the ultimate Heir of all things (Hebrews 1:2).
- The Church is vitally ingrafted into Christ, making us "joint-heirs with Christ" (Romans 8:17).
There is no "separate plot of dirt" reserved for a fleshly lineage. Physical borders, ethnic lines, and localized real estate have been completely swallowed up by the
Glorification Phase of salvation. The land of Canaan was a shadow; the new creation is the reality. If you belong to Christ, you are the true Israel, and the entire universe is your promised estate!
