My pastor here in England told me a good theological joke (yes, there is such a thing).
Augustine, Calvin and Karl Barth are standing before the Pearly Gates, awaiting entrance into heaven. Augustine’s name is called and he goes in. A half hour later he returns. Overjoyed, he reports that he has conversed with God “and I now understand fully the doctrine of the Trinity and the complete meaning of the Incarnation of Christ!”
Calvin is next. He enters and returns another half hour later and exuberantly tells his fellow theologians that he has seen with his own eyes the glory of Christ “and I now understand everything about divine sovereignty and election!”
Barth then enters after hearing his name called from the Gates. A half hour later God comes out and says, “I still don’t understand him.”
