Genesis 19:12 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.
It was Lot who started a conversation with them, because he had learned kindness under the influence and example of Abraham. But the inhabitants of the city were long past their probationary period, and because of this, any warning from God would be rendered useless. It is worthy of note to whom God gave a heads-up, as to what was going to shortly come to pass.
The Lord first revealed what He was going to do to Abraham, who then interceded for the inhabitants of Sodom. But when this failed, God sent angels to Lot’s family, including his children, who had gotten married in Sodom. But the general population as a whole was never given a clue, because their day of grace was over.
Abraham, together with Lot, and his immediate and extended family were all given a heads-up, but the citizens were not made aware of what was coming their way, and that’s because warning and entreaty at this point would have been redundant.
Genesis 19:13 For we will destroy this place, because the cry of them is waxed great before the face of the Lord and the Lord hath sent us to destroy it.
May The Lord add His blessing to the study of His word. God bless!
