The Cross Centered Life: Keeping the Gospel The Main Thing by C.J. Mahaney
Yesterday I rode the metro to DC and back. During the ride, I read this book. Its only 80 small pages long, which is good, because the author doesn't have a whole lot to say. But what he says is important.

I've read the book three times. Each reading has been worthwhile. The premise of the book is that the Christian life has it's beginning an end in the cross of Christ. The gospel that saved us is the gospel that sustains us. This seems basic, elementary, but it's terribly easy to ignore.

After making that argument, the author gives some practical advice on how to keep the cross central in your thoughts and how doing so avoids common pitfalls. I particularly enjoy this section, because, almost invariably, I get distracted and wrapped around the axle on stuff I shouldn't. Refocusing my meditative life is important. Reading this book every year or so helps.
