The calling of Abram in Genesis 12 is a foundational text for Christians. Abram obeys the voice of God by leaving his country and his relatives, and receives a series of remarkable promises which have proved central to Christians. God promises Abram land, offspring and blessings. He promises Abram that he would be the father of a great nation and that his name would be made great. Then, to top it off, God promises that all the nations of the earth would be blessed through him.
