Aside from that last sad conclusion, those who accept a Biblical worldview have a similar understanding of the many religions and deities across the world and history. The idea that spiritual beings would cultivate followings and systems of belief for themselves is even taught in certain parts of scripture. This idea that has trickled into popular culture and fantasy fiction over the past couple decades is nothing new. The difference being that believers would say that these spiritual beings are not merely seeking out worship, they are distracting people from seeing reality.
Beyond the help that this book provides for starting spiritually themed conversations, there is little to recommend it to a Christian readership. Some of the themes and a lot of the language would not sit well with most. Then there is also the disturbing self-examination some Christians would have to perform. There are plenty of people who claim to have a Biblical understanding of God and the world who have just another run of the mill religion. Gaiman sums that sort of thing up well here:
“Religions are, by definition, metaphors, after all: God is a dream, a hope, a woman, an ironist, a father, a city, a house of many rooms, a watchmaker who left his prize chronometer in the desert, someone who loves you—even, perhaps, against all evidence, a celestial being whose only interest is to make sure your football team, army, business, or marriage thrives, prospers and triumphs over all opposition.”
Religion is the sort of thing that happens when you try to understand God on your terms instead of His; that He exists to fulfill your wishes and not the other way around. Some Christians need to ask themselves, “Just who am I in fact worshiping?”
