Science fiction - and the correct shortcut is 'sf' - uses actual scientific facts or theories for the source ideas or framework of the story. It has some scientific content, however speculative. If it breaks a law of physics, it knows it's doing so and follows up the consequences. If it invents a society of aliens, it does so with some respect for and knowledge of the social sciences and what you might call social probabilities. And some of it is literarily self-aware enough to treat its metaphors as metaphors.
Lord, I am no longer my own, but Yours. Put me to what You will, rank me with whom You will. Let be employed by You or laid aside for You, exalted for You or brought low by You. Let me have all things, let me have nothing, I freely and heartily yield all things to Your pleasure and disposal. And now, O glorious and blessed God, Father, Son, and Holy Spirit, You are mine and I am Yours. So be it. Amen.
