1. Yes, those who are saved will want to obey Jesus so you answered your own question.
2. As for the passages, Interpret them in a way in which they do not contradict other aspects of scripture.
You know as well as I do, that Christians say they love Jesus, But don't obey Him.
Heb 6 and 10, do contradict what people say on here. How can you say they don't??.
