Q. Hello, thanks for this blog, I am still confused about the genealogy in the Bible,
we know that Jewish people are linked with Judah (Yahuda)
and Israelis (the twelve sons) are linked with Israel (Jacob)
and Ishmaelites (the Arabs) linked with Ishmael (Ismail)
all those are the sons of Abraham biologically
How do Christian people link themselves with the Abrahamic heritage?
Thank you for your question. Christians do not trace their lineage from Abraham through physical descent, but rather through faith. As the New Testament says, in Paul’s letter to the Galatians, “Just as Abraham ‘believed God, and it was reckoned to him as righteousness,’ so those who believe are the descendants of Abraham. And the scripture, foreseeing that God would justify the Gentiles by faith, declared the gospel beforehand to Abraham, saying, ‘All the Gentiles shall be blessed in you.'” Paul says a little bit later in that letter, “If you belong to Christ, then you are Abraham’s offspring, heirs according to the promise.“
Paul says similarly in his letter to the Romans that Abraham is “the ancestor of all who … follow the example of the faith that our ancestor Abraham had.”
John the Baptist said similarly that what mattered was faith, expressed through repentance and confession. He told some people who thought they didn’t need to be baptized, “Bear fruit worthy of repentance. Do not presume to say to yourselves, ‘We have Abraham as our ancestor’; for I tell you, God is able from these stones to raise up children to Abraham.” In other words, it was not physical descent that mattered, but genuine faith.
So Christians understand from the New Testament that if they trust in God for forgiveness and new life, they are spiritual descendants of Abraham, who set the example of that kind of trust in God.
