What this book lacks in length (its only 60 pages long) it makes up for in depth. Watchman Nee tackles the complicated issue of renewing your mind, an idea and concept that seems to have faded into obscurity in Christian teachings. Nees premise is that Christians must have a renewed mind to understand the things of God, to discern Gods will for their lives, to make decisions and walk by faith. He introduces the reader to the Greek term for the mind or understanding: nous, which according to Nee is used twenty-four times in the New Testament. Then with surgical precision, he explores the concepts of the body, the spirit and the soul as well as diving into the important issue of the heart. While Nee believes that many Christians may have had a salvation experience, they are not walking and living in victory because they do not understand or are not willing to renew their minds everyday, and it is that spiritual discipline that must return to the Christian life the renewing of the mind is an act of the will, an act of obedience and surrender for which we are responsible. God has already given us a new heart and the mind of Christ, but we must surrender of our will to the will of God by renewing our mind consecrating our thoughts to the Lord.Again, while the book is short in length, it took me quite a while to read through it because of the nature of the material and Nees writing. He seems to be saying the same thing in a variety of ways to get his point across, but in the end youll be glad you stuck with it and finished this wonderful spiritual gem. I believe Nee is absolutely correct and that this concept of renewing the mind is the proverbial lost art in Christianity today we learn so much, have access to so much information, but seem to use so little of it Nee would say its because our minds are dirty, unfit for Gods use and we need to renew our minds daily to prepare us for service to God.
