The sixth book in the list of booksthat you've never heard of but need to read is by another old dead guy. It'sRare Jewel of Christian Contentment by Jeremiah Burroughs. Because it was written in the 1600s, you'll struggle with its tempo and style. I actually reviewed it on the blog back in 2010:

Rare Jewel of Christian Contentment is a ponderous read. I’ll admit that at the beginning. It’s not full of witty anecdotes or alliteration. It’s depth, however, has made me compare other current Christian books I’m reading to wearing floaties in the baby pool...

In a Mini-Cooper society as ours, his book reveals that we also have mini-souls. We are so easily discouraged. We have become content with being discontent. He offers chapter by chapter, practical and spiritual advice for pursuing and seizing a distinctly Christian contentment.

He urges all of us to get out of the shallow end and go deep into contentment with Christ. It requires a ruthless self-examination of all that we are currently seeking contentment in. He then urges us to press higher (and deeper) by seeking our heart’s contentment in only those things designed to truly satisfy our hearts.

If contentment is something that eludes you, or if you fear that yours is a shallow, uninformed kindergarten contentment, I’d urge you to pick up a spade and dig in the Rare Jewel of Christian Contentment.

If you're ready to press deeper in your relationship with God and discover what it means to choosegenuine soul rest, this is the book for you.
