I was a bit skeptical of this book when I heard of it, but I'm quite impressed.
It's a daily devotion that quotes from Shakespeare, provides a relevant passage from the King James Version of the Bible, and then offers some commentary on either the one or the other or the way the two speak to each other.
I've been using it in my Shakespeare class this semester, and I think it went well. Before I realized how the book is organized, I was providing the reading for the day of the year. Since the class meets on Mondays, Wednesdays, and Fridays, that meant that I was skipping nearly every other day. It worked much better when I figured out that (generally) each play has its own grouped set of days and quotes from each play progress from early to late in the play. I realized that in time to focus on readings from King Lear during our class on King Lear, and I think that was quite effective.
Each reading concludes with an application question and some additional information—sometimes about Shakespeare's vocabulary, sometimes about modern responses to or versions of the plays, sometimes about the world around Shakespeare.
Here's a sample from early October with some words from King Lear:
I think I'll use this with a class again, but I'll ignore the days and stick to the plays (in other words, I'll read the Macbeth devotions even if it's February).
