The Bible teaches that being a child of Abraham is not based on physical descent but on faith in Christ.
In Matthew 3:9, the emphasis is on the distinction between physical lineage and spiritual heritage. The Apostle Paul further expounds this in Galatians 3:29, stating that 'if you are Christ's, then you are Abraham's seed, and heirs according to the promise.' This indicates that those who have faith in Christ, regardless of their ethnic or cultural background, are considered the true children of Abraham. Therefore, true lineage to Abraham is founded upon a relationship with God through faith, not mere biological descent.
