The book is a companion to a painting, which was inspired by a meditation on Revelation 22, wherein is described the Tree of Life. 

Originally developed as a source of hope for the dying, the painting and accompanying interpretation took on a universal application, since all individuals will eventually pass through the Valley of the Shadow of Death. Those who embrace the Gift of Eternal Life offered by our God will look forward to passing out of the Valley, to be raised imperishable to enter God's presence in the Celestial City for all eternity.
