When I picture Abraham standing and talking to the Lord, I wonder if he is counting Lot's family in his mind? Wouldn't he think to bring them back to him and destroy the cities as was the final outcome? As it was there were not even 10! And even after their salvation, had not Lot told his daughters how close their kinsmen were? When Abraham looked and saw the cities burning, did he wonder if "there were none righteous, no not one?" such great description in this narrative and so few answers.
Abraham asks the question, would the righteous be destroyed with the unrighteous? The righteous will live with the unrighteous until that day, with the possibility that they won't be destroyed. The fields are white unto harvest!
I think I will try setting the Proverbs reading to memory: For the Lord gives Wisdom...
