I found a link to some free books you can read in PDF files online by D. A. Carson. One of them is a fairly short book (93 pages) entitled The Difficult Doctrine of the Love of God that was written from several lectures he gave on this subject. An excerpt explaining why the doctrine of the love of God would be described as “difficult”:
Suddenly the Christian doctrine of the love of God becomes very difficult, for the entire framework in which it is set in Scripture has been replaced. To put this another way, we live in a culture in which many other and complementary truths about God are widely disbelieved. I do not think that what the Bible says about the love of God can long survive at the forefront of our thinking if it is abstracted from the sovereignty of God, the holiness of God, the wrath of God, the providence of God, or the personhood of God—to mention only a few nonnegotiable elements of basic Christianity.The result, of course, is that the love of God in our culture has been purged of anything the culture finds uncomfortable. The love of God has been sanitized, democratized, and above all sentimentalized.
This process has been going on for some time. My generation was taught to sing, “What the world needs now is love, sweet love,” in which we robustly instruct the Almighty that we do not need another mountain (we have enough of them), but we could do with some more love. The hubris is staggering.
He goes on to say that is isn’t just the world that believes incorrectly about the love of God. Unfortunately, we often hear a one-sided view of God’s character even from believers. This is a really good book that will get you thinking about what you believe about the Biblical teaching of the love of God and how that affects the way you view Him.
Take a few hours and read this book. I think you will enjoy it!
