Question: Last summer in a small conference in Pennslvania, you quoted this sentence from Martin Luther: “For a man becomes a theologian by living, or rather, by experience, death and condemnation; not by mere understanding, reading and speculation.” Can you tell me what book it was in?

Answer: Thanks for writing! What a great quote. It comes from Luther’s second psalm lectures (the Operationes in Psalmos), in the midst of commenting on Psalm 5. You can see the quote on page 266 of this translation: https://archive.org/details/lutherscommentar01luth/page/266/mode/2up.
