Puritan writings typically fall into two camps, lots of depth, ala John Owen, or straight to the point, ala Thomas Watson here. What this book may lack in depth, it makes up for by going straight to the heart and soul with challenging, encouraging, and gracious exhortation to deny self and serve Christ. Oh how many ways Watson points out how selfish I am. I could have stopped at the first one and spend the rest of my days repenting, yet he keeps piling on more. Thankfully the Holy Spirit grants grace and strength to repent and obey.
