Heritage is powerful. God saved Lot because of his family heritage through Abraham. If it wasn’t for Abraham’s intercession, Lot would have destroyed along with Sodom.
Everyone who knows the story of Lot remembers that his family became enemies to Israel. God pronounced judgement on them. The godly heritage of his uncle, which could have been passed on, was destroyed.
Why? Because of Lot’s choices. He chose the better fields, subsequently, “pitching his tent toward Sodom.” (Gen. 13:8-13) He later lived in the city of Sodom and would have gone up in flames with it if it wasn’t for Abraham. (Gen. 18:22-33)
