What does the Bible say about natural ancestry and God's mercy?

In biblical accounts, such as those found in Genesis 46, we see that God's mercy and benefits are not limited by natural descent or lineage. For instance, the presence of both Egyptian and Israelite bloodlines, as seen with the sons of Joseph and the mention of Judah's children, highlight that God's mercy transcends ethnic and ancestral ties. The New Testament reinforces this idea in Romans 2:28-29 where it states, 'For he is not a Jew who is one outwardly, nor is circumcision that which is outward in the flesh; but he is a Jew who is one inwardly.' This teaches that a true relationship with God is based on His grace, not human lineage or merit, emphasizing the universal need for grace across all peoples.
