I highly recommend this book, Dusty Shoes, Rolled-Up Sleeves and other Signs of Life – Back to the Basics of Authentic Christianity by David Jeremiah. I think it is easy to become a stale Chrisitan that we so often hide our light to the world. This book helps to motivate/encourage how we should live and act and reach out to others. If you do not like to read a lot, you are in luck because it is written so that there is a daily reading for forty days. Each reading only amounts to a few pages. When I first read this book it had a huge impact on me and recently I have been struggling with some personal circumstances, knowing that through my struggles I still need to allow my light to shine and show my joy of salvation to the world. This book, once again, is helping me to do just that. So, if you are looking for something to motivate you in your Christian walk then I recommend this book for you.
