John Piper is my favorite contemporary Christian author, so it was no surprise to me that this would be another engaging, worship inspiring work from him. His longer works such as "The Pleasures of God" are amazing when you have a bigger stretch of time for devotion, but this provides a perfect alternative when a larger work might put one off from even getting started. Each meditation is a bit longer than a given entry from say "My Utmost For His Highest" (quite possibly the quintessential daily devotional book), but still easily manageable in a single sitting.
