King James Bible
"And if ye be Christ’s, then are ye Abraham’s seed, and heirs according to the promise."
Paul establishes belonging to Christ as the sole condition for inheritance, emphasizing that union with Christ transcends ethnic or religious boundaries. This phrase directly challenges the Judaizers' insistence on circumcision and law-keeping for gentile inclusion. Those who belong to Christ become Abraham's true descendants—not through physical lineage but through faith, fulfilling God's promise that Abraham would father many nations. This revolutionary claim redefines Jewish identity around Christ rather than ethnicity. Believers inherit the blessings God promised Abraham—justification, the Spirit, and eternal life—not through law but through the same faith Abraham exhibited. This concludes Paul's argument that the gospel has always been about promise and faith, not performance.
