I invite the reader to not only read Walther's sermons in a devotional time (as I have in a family setting), but also search for some specific topics he has covered in this book. I made two listings below as I went through Walther's Year of Grace book: 1) Quotes and (2) Search Terms. Neither of these are exhaustive. Please note that Part 1 contains pages 1-180, while Part 2 contains pages 181-362.
May God bless the reader's use of Walther's sermons!
