Primer to Desiring God

I'm finishing up a paper on Desiring God by John Piper. Our assignment is to respond to this critique published by Rev. Peter Masters in 2002. I learned that the audience for my essay is one who has already read Desiring God, such that I am not supposed to spend a great deal of time explaining the book's thesis. Since I had to pull that material from my paper, I thought I'd post it here for the benefit of any who may not have yet read Desiring God. Here it is.
