Is Les judging the people he is teaching about in Romans 1?
No, the teaching is not judging. It clarifies that it is not looking down its nose or judging but simply showing what Scripture says, as God builds His case like a prosecuting attorney against all humanity, beginning with the immoral.
Les explains that from Romans 1 through chapter 3, God is building His case against the whole human race like a prosecuting attorney. He categorizes humanity into three groups: the immoral or amoral, the moral, and the religious. The conclusion for all three is guilty, leading to Romans 3: none does good, none does righteousness, all become unprofitable. Les emphasizes he is not looking down his nose or judging; he is simply showing what Scripture says as God builds His case, starting with the most obviously guilty—the immoral who have no morals.
