God's hand points Abraham to the countless multitude of stars. So numerous shall his descendants become. Hard to believe back then, but today unmistakable: Three world religions claim Abraham. As the patriarch of Israel, he stands at the cradle of Judaism. From Paul to the present day, Christians have learned from his example what it means to believe. In Islam, he is regarded as a perfect Muslim who has unreservedly submitted to God's will. In his memory and in honor of his sacrifice, the annual pilgrimage with its rituals is observed. The construction of the sanctuary in Mecca is traced back to him as the founder of the cult. These various interpretations are based on what the Bible narrates about Abraham and Sarah in Genesis 12-25. These texts are pearls. Matthias Köckert's highly readable and fluidly written book invites readers to discover their literary beauty and appreciate their immense impact.
