Biblical speculative fiction is speculative fiction that uses Christian themes and incorporates the Christian worldview. (It is thus distinct from speculations on the Bible and/or Christianity such as Dan Brown's The Da Vinci Code.) The difference between biblical speculative fiction and general Christian speculative fiction is that the Christian nature of the story is overt. This represents the tension in the Christian fiction community between those who prefer stories that reflect a Christian worldview without explicitly Christian references (such as The Lord of the Rings), and those who prefer the more overt Christian material usually found in the works of G. K. Chesterton and C.S. Lewis. Current examples of these views may be found in the explanatory page of Ray Gun Revival, a magazine
