In a sacramental ecology, divine grace is to be found in the evolutionary emergence of life. The 'Epic of Evolution' is the scientific story that reveals that we live in an approximately 14 billion year old universe on a planet that is approximately 4.6 billion years old and that we are a part of the ongoing process of life that has existed on Earth for roughly 4 billion years. Nature's Sacrament focuses on the religious and ecological significance of the evolutionary epic in an effort to seamlessly connect the ecological value attributed as a part of an understanding of the evolutionary connectedness of life on Earth, with the Divine grace understood to be present in Christian sacramental worship.
