Until I read this book I would not have considered God’s love as a particularly difficult doctrine. The Trinity is a difficult doctrine to understand, impossible even. The eternal nature of God—that is another difficult or impossible one. But the love of God? I wouldn’t have thought of it as such. But this book convinced me otherwise.
The Difficult Doctrine of the Love of God by D.A. Carson is just a short book (96 pages) that is drawn from four lectures he delivered in 1998. There was a small amount of editing performed, but the conversational nature of the speech carries through the text. It makes for an easy read, despite some deep theology.
