Luther on the third use of the law

For those who deny that Luther had any "third use of the law" look at this text from his sermon on Matthew 22:34-46 from 1533:

"We dare not neglect the catechism's teaching of the God-given Ten Commandments as an insignificant doctrine, but must diligently use it in teaching people how they must live this earthly life. Of course, showing them how to be saved takes an entire different doctrine than the Ten Commandments, namely the doctrine of Christ, which our Lord presents a little later. But you must use the Ten Commandments to teach people how they must live in this life."
