He spoke about what it means to have the name Christian.
“Believing in Christ is not sufficient today to be a Christian,” he said. “… It is also essential to believe Christ, believe what He taught, what He told us to do and then do it. If you do what the Lord wants you to be doing, you’re going to be good at it, and it will be very rewarding.”
Gresham also spoke about moving to England and meeting Lewis as an 8-year-old boy who was already very familiar with the high adventures of Narnia.
“The man was on speaking terms with my King Peter. … I expected a knight wearing silver armor and carrying a sword. … It was absolutely nothing like that at all. … He was dressed in the most shabby clothes I had seen in my life, but his huge personality and his great sense of fun soon eradicated any physical deficiencies that might have been in his appearance. I learned that sometimes we can lose an illusion and gain a treasure. … I gained what became a very fine stepfather.”
At the end of his talk, he did a question-and-answer session with students. Questions ranged from whether the Chronicles of Narnia are a mere allegory, to if he had met J.R.R. Tolkien, to whether all of the Narnia books will be made into movies.
