I've read a lot of Christian books. Growing up in the church, Christians are already very prone to be "booky" people. And couple that with my love of reading, and I've become a Christian book consumer. But this one stands alone.
Perhaps it was the timing of my reading it: I was a Freshman in college. I have always struggled to balance legalism with license to sin (anti-nomianism). The Discipline of Grace is all about staying out of these two ditches on either side of the road that is the Christian life. I struggled because I wanted to pursue godliness and holiness so much, but found myself doing it to gain God's approval. And in other seasons, I would almost justify my continuing sin by banking on God's grace. Enter this book.
Bridges shows how grace actually teaches and trains us (Titus 2) and we actually use the good news of the gospel and the love God has already given us to motivate us to pursue holiness. It's a high view of grace/justification and high view of holiness/sanctification. I had never heard this message in my entire life.
Preaching the gospel to yourself has become my mantra for my entire life since reading this book. I try to get it into as many hands as I can.
*A great companion book to read alongside this is "A Gospel Primer" by Milton Vincent - which was actually written as a response to this book.
God bless you, Jerry Bridges.
