This book investigates the compatibility of materialism with philosophical theology by proposing a model of a developing, kenotic deity. Peter Forrest, a philosopher of religion, argues that traditional notions of divine immutability are insufficient. He utilizes a framework that reconciles materialist ontology with the concept of a God who evolves through an intentional abandonment of power, known as kenosis.

Scholars of philosophy of religion recognize this work as a rigorous contribution to process-oriented and speculative theology. Readers frequently note the high level of technical philosophical density required to engage with Forrest's arguments.
