In both genealogies of Matthew 1 and Luke 3, Jesus is listed as a direct descendant of Abraham.
In the broadest sense, as the Apostle Paul tells us, all who believe in Christ and follow God's law, exhibiting righteous faith like Abraham did, are part of his family - circumcised or not:
Romans 4:16-17New International Version (NIV)16 Therefore, the promise comes by faith, so that it may be by grace and may be guaranteed to all Abraham's offspring Ânot only to those who are of the law but also to those who have the faith of Abraham. He is the father of us all.17 As it is written: I have made you a father of many nations.[a] He is our father in the sight of God, in whom he believed Âthe God who gives life to the dead and calls into being things that were not.
Footnotes:
Since the Jews believed that they were all, without exception, descended from the legendary Abraham, they could all be called sons of Abraham. Thus Jesus was the "son of Abraham".
Ishmael was the son born to Hager , Abraham's slave, and as Abraham is the father of the Jewish nation, and Jesus was a Jew, he is related.
This appears in the Gospel of Matthew. Matthew's genealogy in Chapter 1 shows that Jesus descended from Abraham.
Abraham did not actually sacrifice his son so your question is meaningless.
The book of Matthew has the geology of Jesus Christ.
Abraham had several wives Sarah, Hager and his sons were Isaac and Ishmael.
According to the Old Testament text, Abraham's first son was Ishmael.
No.. Jehova, the God of Abraham, Issac and Jacob is God the father and Jesus the Son.
Christianity and Islam both have roots in Judaism. Abraham's son Issac was the ancestor of Jesus. Abraham's son Ishmael was the ancestor of Muhammad.
Jesus is considered a central figure in Christianity, believed to be the son of God and the savior of humanity, whereas Isaac is a significant figure in Judaism, considered the son of Abraham and Sarah. Jesus' teachings and ministry focused on love, forgiveness, and salvation, while Isaac's story is more about his birth, sacrifice (nearly being sacrificed by Abraham), and his role in the lineage of the Jewish people.
The first mention of "Jesus" [ie Saviour] is in Matthew 1:1 of the New Testament :-Mat 1:1 The book of the generation of Jesus Christ, the son of David, the son of Abraham.
