A few years ago, I got this book and absolutely loved it. I now get back into it every year at Christmas time. It is an advent devotional book. Nancy Guthrie has taken sermon excerpts from many of the greats and compiled it into one wonderful small volume. Some of the people she has taken from are Charles Spurgeon, Saint Augustine, John MacArthur, John Piper, Joni Erickson-Tada, Martin Luther, and so on. It is phenomonal!
You can buy it here on Amazon for $8. I really recommend this book.
