There Is the Will of God and There Is the Will of God
John Piper on the Two Wills of God:
“There are two clear and very different meanings for the term ‘will of God’ in the Bible. We need to know them and decide which one is being used [when we talk about God's will]. In fact, knowing the difference between these two meanings of ‘the will of God’ is crucial to understanding one of the biggest and most perplexing things in all the Bible, namely, that God is sovereign over all things and yet disapproves of many things. Which means that God disapproves of some of what he ordains to happen. That is, he forbids some of the things he brings about. And he commands some of the things he hinders. Or to put it most paradoxically: God wills some events in one sense that he does not will in another sense.”
