One of the greatest theologians that ever lived, Karl Barth, was asked to be a guest lecturer at the University of Chicago Divinity School. At the end of a captivating closing lecture, the president of the seminary announced that Dr. Barth was not well and was quite tired, and though he thought that Dr. Barth would like to be open for questions, he shouldn’t be expected to handle the strain. Then he said, “Therefore, I will ask just one question on behalf of all of us." He turned to the renowned theologian and asked, "Of all the theological insights you have ever had, which do you consider to be the greatest of them all?
It was the perfect question for a man who had written literally tens of thousands of pages of some of the most sophisticated theology ever put into print. The students held pencils right up against their writing pads, ready to take down verbatim the premier insight of the greatest theologian of their time. Karl Barth closed his tired eyes, and he thought for a minute, and then he half smiled, opened his eyes, and said to those young seminarians, "The greatest theological insight that I have ever had is this: "Jesus loves me, this I know, for the Bible tells me so."
