As the title suggests, this book consists of a series of dialogues between a fictional Christian and a series of equally fictional believers in other worldviews: a pluralist, a humanist, a Hindu, a Muslim, etc. In each case, the Christian tries to explain why even a very positively presented version of the worldview in question is ultimately insufficient. The book also takes three later chapters to allow all the other characters to question the Christian. Currently, the manuscript for this book has been sent to a couple publishers, but no one has yet accepted it. Indeed, I don’t expect anyone will. So I will begin posting chapters here and add more as I revise them once again.
