Philippians 2.13 "'Work out your salvation with fear and trembling; for it is God who is at work in you, both to will and to work for His good pleasure,' which made God the will beneath my will and the worker beneath my work. The question was not whether I had a will; the question was why I willed what I willed. And the ultimate answer – not the only answer – was God." - John Piper
