Abraham, originally called Abram, is the great patriarch through whom God promised to form a chosen people and bring blessing to all nations. Called from his homeland to journey to Canaan, Abraham lived by faith while repeatedly learning to trust God's promises. God pledged to give him descendants, land, and a worldwide legacy of blessing. Despite Abraham and Sarah's advanced age, their promised son Isaac was born. Abraham's willingness to offer Isaac in obedience to God became one of Scripture's most memorable demonstrations of faith. Jews trace their covenant ancestry through Abraham, while the New Testament presents him as a model of justification by faith.
