From God's surprising call to Abraham to leave home and family to God's enigmatic commands that he evict one son and sacrifice another, Genesis 12-25 is one of the most dramatic stories of the Old Testament. In an inviting style that showcases his literary discernment, theological sophistication, and passion for the biblical text, Terence E. Fretheim guides readers through the intricacies of the plot.

Abraham, called "the father of a multitude" (Gen 17:5), lives up to his name as the patriarch of three major religious traditions. Fretheim examines Abraham's family and assesses the significant roles it plays across Judaism, Christianity, and Islam. In addition, Fretheim contributes to the increasingly important interreligious dialogue surrounding Abraham by examining the continuing conversation among Muslims, Christians, and Jews about the place of Hagar and Ishmael in Abraham's family.

Relating biblical narrative to theological concerns, Fretheim wrestles with such controversial concepts as God's selection of an elect people, the gift of land and other promises, the role of women and outsiders, the character of God, and the suffering of innocents. Throughout the text, Fretheim frames the narrative as rooted in the trials of family and faith that define Abraham as the father of three religions.
