Genres: Christian

In simple words, the novel penned by a Christian worldview, a way of viewing the world separated through the facts shown in the Bible, is called Christian books. It implies a sovereign God who made everyone and everything; it believes we are responsible to God for our decisions, promises, and activities; it feels we require forgiveness and redemption and that it comes only through the person of Jesus Christ.
There are two types of Christian Books:

Christian fiction

Christian fiction books are those books that overtly display elements of Christianity in the story, mixing things like prayer, conversion, church.

Christian non-fiction

Christian non-fiction is normally overt in its use of Biblical beliefs to explain an appropriate subject.
