I write inspirational fiction, in which the main characters live with a Christian mindset.
Inspirational fiction has progressed from safe and syrupy to real-world drama. The characters tackle their challenges through a realistic plot, action, and emotions.
Do not expect the plot to halt while I get on my soap box or explain the plan of salvation to a character. I was amused, in fact, when a character in one of my novels, broken with the weight of his life gone awry, confessed his need for a relationship with God. That wasn't planned at all. And it hasn't happened in a novel of mine since then.
Another thing you can expect from inspirational fiction is a satisfying ending. You should be able to close the book (turn off the e-reader) with a sense of peace, happiness for the characters, and a satisfying conclusion.
