In my craving to be happy, I acknowledge that at the center of my life there is a gaping hole of emptiness without God. This hole constitues my need and my rebellion at the same time. I want it filled, but I rebel at God's filling it with Himself. By grace, I awake to the folly of my rebellion and see that if it is filled with God my joy will be full.
- p. 164, Desiring God: Meditations of a Christian Hedonist by John Piper
The Goodnews is not that you are given a way to salvation by obeying the law. It is not even that you can come to serve God simply by you toiling away. The radical nature of the Goodnews is that God is here to serve you in a way that is glorifying to Him and joyful for you.
