Judgement was about to fall on those two infamous cities Sodom and Gomorrah (Genesis 18) ,but Abraham's nephew, wife and family lived there,Abraham prays a prayer indeed pleads for the cities to be spared, if there were just ten righteous people dwelling there,Alas there wasn't even ten,so judgement must fall,but there was one righteous man Lot (2 Peter 2v 2-8) plus his wife,two daughters,and their husbands (2 Peter 2 v 2-)only three of them would be saved.His sons-in-law did not take the warning seriousaly,in fact they laughed,(19 v 14) The Judgement of God is not something to laugh at ,we must take it very ,very serious,for God means what He say's.Hell is not a made up thing,no it is something that God has prepared initially for the devil and his angels,now it includes unrepentive sinners.Consider what Jesus said in Matthew 10v 28,' Do not be afraid of those who kill the body,but cannot kill the soul . Rather, be afraid of the One who can destroy both soul and body in hell'.
'Laughing will one day turn to weeping and wailing'
