Genesis 19:12 - Delivered on behalf of another.

And the men said unto Lot, Hast thou here any besides? son in law, and thy sons, and thy daughters, and whatsoever thou hast in the city, bring them out of this place:

Just as Noah's family was spared from the destruction of The Flood (Genesis 7:1) and Rahab's family was saved during the invasion of Jericho (Joshua 6:22), Lot's family was offered deliverance from the overthrow of Sodom and Gomorrah. It is good thing being akin to those that God favors. The only reason Lot was rescued was because God remembered Abraham (Genesis 19:29).
