This story is inclusive of theology, astronomy, physics and other disciplines to emphasize that not only is God infinite but is the Creator of many worlds in different times and different universes. God has decided to permit two people to see his magnificent creations because as the Creator, he loves all his creations.
The purpose of this story is to expand and challenge the thinking of those seeking a full understanding of religion, God, and the Universe. Is it not comprehensible that there are other worlds and others who will be with God? The last line of the story begs the question: who are the 'others?'
A 13.81-billion-year-old universe makes the comprehensibility of the story plausible as ultimate reality. Additionally, given this small and not-very-old Earth (relatively speaking), why would God just create here?
In the Expanded 2d Edition, the book begins with God explaining creation and that there are other worlds unknown to us. Other profound theological issues are addressed by God through his “typist” (the author). At creation there was nothing but God and afterwards all that is began in the ‘first instant.’ He explains that we cannot fully understand because we cannot conceive of ‘no time’ or what is truly His eternal nature. After all, creation is when space, matter, and time came into existence.
The 'worlds apart' exist at different stages of time and space so that "eternal" is timelessness. None is aware of the others existence which occurs over millions of years.
There is no evil or devil in this story. God is the central character. The text speaks to all religions.
This is not pantheism, rather theism at its most profound. The story is designed to open thoughtful conversations about God and humankind. The Latin phrase at the conclusion of the book means “Heaven at last” and comes from history.
