I've never read this before. Seems to me that gullible folks will believe whatever they want to believe, but if you get a serious person with a relatively open mind who wants to discuss this story on its merits from a Christian perspective, one discussion point you might raise is the issue of whether the version of Christianity represented in this story turns "belief" into a form of merit-making and turns Jesus into an irrelevancy. Especially this chuckle-provoking paragraph:
I was told to look at another person who was in the fire. I saw a man with very long hair wrapped on the left hand side of his head. He was also wearing a robe. I asked the king of hell, "Who is this man?" He replied, "This is the one you worship: Gautama [Buddha]." I was very disturbed to see Gautama in hell. I protested, "Gautama had good ethnics and good moral character, why is he suffering in this lake of fire?" The king of hell answered me, "It doesn't matter how good he was. He is in this place because he did not believe in the Eternal God."
Gotama lived before Jesus Christ. So you could ask your friend: For people who lived before Jesus, how was salvation possible? If salvation already was possible through belief in "the eternal God," then why did the world need Jesus? And if salvation is possible as a consequence of one's belief, doesn't that contradict the New Testament teaching that salvation is by grace, "so that no man may boast"? And that "faith" is not from oneself? Doesn't that make one's beliefs a form of merit?
I think a sensible response might be in order if you think you have a receptive audience. But if the audience isn't going to listen, then don't waste your time.
