Gods do four things: they define truth, they define life, they define good, and they define safety. Nate Wilson explains how to use these four "functions of deity" to identify who your god is, recognizing that opinions vary widely as to what kind of being fulfills the functions of deity. Nate aims to talk sense into the heads of both Christians and athiests alike by examining the roles that gods play in epistemology, ontology, ethics, and soteriology. He draws conclusions about what makes for a good god and what makes for a... not-so-good one.
