God is angry—furious—with a particular sin. When we examine that sin, it is seen to be both ungodly or irreverent and unrighteous or immoral. Ungodliness and unrighteousness are vast generic terms that cover a multitude of sins, but Paul is not talking about a multitude of sins here. He has in view one particular sin. It is a universal sin, one committed by every human being. It is the sin that most clearly expresses our Adamic nature, our corruption and fallenness in the flesh.
