The conditions to become an heir

 "Get out of your country, from your family and from your father’s house, to a land that I will show you." Genesis 12.1

Abraham had to leave his land, his family and the position of leadership inherited from his father.God required him to sacrifice. And those who want to be sons and heirs of Abraham must pass the scrutiny of sacrificing this world. The Lord God must come before than nationality, relatives and our father's house.
