I'm reminded of the story of Lot and his wife when God told Abraham that he was going to destroy Sodom and Gomorrah because these cities were doing wickedness in His sight. Now Lot knew these cities were sinful but still was willing to tolerate sinfulness by allowing for him and his family to remain there for selfish gain. Lot was for social and material advantages and probably felt his family could remain faithful unto God in the midst of the sinfulness in the cities. However, saints God tells us in "Hebrews 10:25 (New Century Version) You should not stay away from the church meetings, as some are doing, but you should meet together and encourage each other. Do this even more as you see the day coming."
Even in the midst of Lot and his family living amongst the sinful cities, God showed mercy on them because of Abraham's prayer unto God on their behalf. God sent forth angels to warn them of the coming destruction to the cities because of the sinfulness and wickedness. They were instructed by the angels to leave immediately. Lot and his family hesitated to leave immediately so the angels assisted them by getting them out of the city quickly. They were instructed not to look back as the city was being destroyed (Genesis 19:17). As they were fleeing the city, Lot's wife looked back and when she looked back she turned into a pillar of salt.
