Genesis 19:14

So Lot went out and spoke to his sons-in-law, who had married his daughters, and said, “Get up, get out of this place; for the Lord will destroy this city!” But to his sons-in-law he seemed to be joking. (Genesis 19:14 NKJV)

Do you feel like this sometimes? You try and seriously let someone know that they are going to die for their sin and they don't take you seriously? The angels of God were giving a last chance for those wanting to be delivered and Lot was being faithful to call them out. Be faithful. Give last chances. Maybe they will react better than Lot's son-in-laws.
