Where is wickedness worse than in America today?
Wickedness and sinfulness are worse in other areas of the world than in America today. The context notes that horrible wickedness, sinfulness, and evil are being practiced, not so much in America yet, but more so elsewhere, prompting wonder at how God endures it before His wrath comes.
Les explains that when he reads of the horrible wickedness, sinfulness, and evil that men are practicing, it is not so much in America yet as in other areas of the world, and it makes him wonder how God can put up with it. He says he could hardly sleep at night to think that men can get so low in their sin. He then connects this to the coming wrath of God on sinful men, and to the Tribulation, a time of trouble unlike any before, for which all the world is getting ripe.
