Science Fiction has always had a Leftist component, sometimes with a little balance from liberterians.
There are very few conservative oriented Science Fiction books. I am trying to think of some.
Perhaps someone can help me out with that.
In fantasy, perhaps the Lord of the Rings Trilogy...
Short range SF now occurring “The Camp of the Saints”.
Kurt Schlichter’s People’s Republic series.
Matt Braken’s Enemies Trilogy.
The Weapon Shops of Isher... More liberterian than Conservative
So, there are some. Where are those which incorporate Christian faith in the story?
Off the top of my head I would say Gene Wolfe. I great writer strong conservative and devote Catholic. I enjoyed talking to him at the Chicago area sci fiction conventions and was sorry when he moved to Peoria.

I know for a fact he was strongly pro life.
A lot of people consider Harrison Bergeron to be a conservative Science Fiction story, even though it's writer, Kurt Vonnegut, was not considered conservative.
Also, Nineteen Eighty-Four might be considered some, even though Eric Blair was not a conservative, he grew very opposed to communism.
The classic science fiction of C.S. Lewis is of course pro Christian:

Most dystopias are anti-left in one form or another. They usually show central planning that goes awry.
The science fiction organizations followed Robert Conquest’s Second Law:
“Any organization not explicitly right-wing will eventually become left wing.”
They get nuttier every year.
Like all his work these are great reading, though very different from what a normal SF fan would expect. Partly due to the difference in worldview, and partly just because he was writing in the 1940's when ideas about other worlds had little scientific basis to go by.
I would particularly recommend That Hideous Strength, which in my opinion is a much better book than 1984, while covering the same ground. I'm not the only one who in recent years has expressed the thought that we are living out the world depicted in That Hideous Strength.
All Heinlein’s works are slanted rightward. In that era of classic sci-fi, it was largely considered to be a right wing subgenre.
Ender’s Game
Larry Correia (I’m waiting for his ripping on this) has some sci fi stuff, he’s freedom loving, mormon too but I dont hold that against him. Baen Books has several authors that are conservative, libertarian bent, but they are freedom of ideas so they have some lefty authors too—some are good too.
Authors rather than specific books: Larry Correia, John Ringo, Michael Z. Williamson. There are others.
Robert Heinlein could be considered conservative, though I think of him more as a libertarian.
A few names come to mind: Jerry Pournelle, Larry Niven, Ben Bova, Keith Laumer, Gene Wolfe, Gordon Dickson, Dean Ing, David Drake, Robert Heinlein (up to about Stranger in a Strange Land, then he went to Hell). A lot of these writers were somewhere in the conservative to libertarian range, but as you can see there is a shortage of *living* contemporary conservative SF writers. As with actors in Hollywood, it’s not that there aren’t writers whose personal politics aren’t conservative, but most learn early on that they’d better keep their mouths shut if they want to have a career. The Fruits & Nuts Faction did a really good job of making examples of Orson Scott Card and J.K. Rowling. Aside from people like Jon Del Arroz, who seems to thrive on it, no one wants to draw the attention of the crazies.
