Why do Jews think Abraham is their farther?

Jews consider Abraham their patriarch because he is a central figure in the Hebrew Bible, particularly in the Book of Genesis. According to Jewish tradition, God made a covenant with Abraham, promising him that he would become the father of a great nation, which is understood to be the Jewish people. This covenant established a foundational relationship between God and Abraham's descendants, making him a key ancestral figure in Judaism. Additionally, Abraham's faith and obedience to God serve as a model for Jewish beliefs and practices.
