is a story that uses the medium of science-fiction to explain Christian concepts. People of the future travel to a distant planet, Giannes, where they plan to establish a Christian colony. The plan is sabotaged by some evil entity.
The story explains the origin of human evil in our first parents, Adam and Eve. It explains how the human race, descended from the first couple, is an entity.
The story explores the possibility that God might create other intelligent beings.
Might they, too, be fallen; or might they be without sin?
The colonists make great use of sophisticated robots. The story makes clear that no matter how like a human being a robot might seem, no robot can ever be a human being. Only human beings have spiritual souls created by God.
There is much more Christian teaching, set in an exciting space adventure.
It makes one very important point: that theres is no conflict between the Christian faith and science. No scientific advance can ever "disprove" Christianity, for God is the author of both.
