How does the concept of the true Israel relate to believers today?

The concept of the true Israel is rooted in Galatians 3:26-29, which explains that all who believe in Christ, regardless of ethnic background, are counted as Abraham's seed and heirs according to promise. The historical nation of Israel serves as a type or shadow of the spiritual reality found in Christ. While physical descent from Abraham does not equate to being God's children, spiritual descent—that is, being born of the Spirit—does. By faith in Jesus, believers today enter into the promises of God and become part of the covenant community that Jesus established, fulfilling the prophetic declarations about God's people. This means every believer can claim the same inheritance promised to the original Israel but ultimately fulfilled in Christ.
