It is somewhat amusing. Kristof is asking Yancey some serious questions about his Christian beliefs.
The funny thing is that Yancey never gives a direct answer. His response is always a diversion away from what was asked.
I can understand why. If he were to give a direct answer, he would either look ridiculous or he would look like a heretic, depending on which answer he gave.
Those answers were so typically Yancey. His theology is equally anemic. It’s ghastly that he has the ear of so many Christians.
