In The Pursuit of Holiness, Bridges reminds us that God commands us to be holy (1 Peter 1:16). We are also told that we have a responsibility to pursue a life that is holy. With the help of the Holy Spirit, we are to train ourselves to regularly practice spiritual disciplines. This of course includes studying Scripture deeply and praying constantly. Bridges' is not saying that our works save us, but He is saying that we cannot sit back and simply live in the same manner as the world. We are saved by faith alone in Christ alone, and if you truly believe that, you strive after holiness. You seek it out. You do not want to be God or worship other "gods", but you desire to be like God, the Holy One of Israel.
The Pursuit of Holiness is divided up into 17 chapters and takes only four hours to complete. Although Bridges is covering a serious topic, the material is presented in a clear and engaging manner. I chose to listen to several chapters more than once. The book is endorsed by a number of people that I enjoy listening to such as Chuck Colson, John Piper, and J.I. Packer. If you desire to learn about God's holiness and how to develop habits of holiness, I highly recommend Bridges' book. It is filled with tons of Scripture, real life stories, and plenty of pertinent counsel.
