Paul uses these questions to present what some people were arguing and to get his readers to think about whether or not this argument is true. Alternate translation: "Some people say that since our unrighteousness shows God's righteousness, then God is unrighteous when he punishes us" (See: [[rc://en/ta/man/translate/figs-rquestion]])
Here "wrath" is a metonym for punishment. Alternate translation: "to bring his punishment upon us" or "to punish us" (See: [[rc://en/ta/man/translate/figs-metonymy]])
