Genesis 19
Lot
Lot was a righteous man but he moved to Sodom. Although his soul was vexed, he stayed. Finally he lost his influence and had to flee. He probably thought he could change Sodom. But there is ever the danger that before you can bring light to Sodom, you will get used to its darkness. Little by little, sin appears less sinful until the “light within us becomes darkness” (Luke 11:35).
