It is clear that the Lord compares the state of men (careless, selfish, godless, guilty, dead also to what He, the rejected Messiah, had suffered for their sake) to that which brought on the two most solemn judgments which Genesis records the deluge and the destruction of Sodom by fire.
Will the revelation of the Son of Man in His day be less righteously called for? No! The last days of the Christian era will be times of excessive, abounding and audacious lawlessness as well as impiety.
