I so enjoyed this book. I've never read anything by John Piper, so this was a treat. I had to read it slowly so that I could truly understand and think through what he said.
The basic idea that I took away from Desiring God, is that we give Him glory by enjoying Him. Just as I feel honored and loved when my adult children enjoy me and my presence, so God is honored and loved when I enjoy Him.
He is everything that I truly crave in life: perfection, beauty, order, joy, love, and peace. All of the things I long for in my earthly life and heart are found in perfection in Him alone.
I will be rereading portions of this book through the months so that I can be often reminded of where my joy truly lies.
