What is the relationship between sex and gender? Robert S. Smith argues that God intends a person's gender to be grounded in the reality of his or her biological sex - the body God has given.

In making the case he critiques the central claim of transgender theory, that the sexed body does not determine the gendered self, and evaluates the contemporary changes in thought and speech that have followed from it. A full-length academic treatment rather than a popular one, and the most thorough evangelical engagement with the literature currently in print.
