This is an open section of the writing area which means that anyone may contribute, Christian or nonChristian, writer or nonwriter. However, this is an area set aside specifically for Christian authors. So, at the minimum, threads should be about literature and at least respectful of Christian values and principles.
This forum has a robust section for debating the evidential merits of Christianity- and this is not it. This section might be an appropriate place to discuss methods of discussing those merits (the written word being an obvious favorite) but posts that move beyond that will be deleted or moved to the appropriate place.
It is strongly suggested that you be wise in sharing your stories and story ideas. That may be better in the 'Committed Christian Author' section (which you have to request access too) where the member group is carefully screened.
