Texts that deal with Biblical information and themes have long been popular with readers. In fact, publishing a Bible often anchors a publishing house with a text that continues to generate sales year after year.
This leaves the arena wide open for authors writing Christian-based works. In addition to novels that deal with spiritual topics, the nonfiction area is strong. Topics can be academic in nature or geared toward mainstream audiences reading at home on their own.
Keep an eye on titles that are coming out to determine which publisher is best for your Christian work.
