Do you have to be Christian or a strong believer to write for the Christian Market?
No. They’re looking for great stories and high-quality writing skills. They of course want to convey a certain message but it’s not required that you follow the press or publication’s own set of beliefs to submit.
Do write well, and make sure your message is in line with theirs.
Keep the stories uplifting and inspirational!
Be open to feedback (as always) and you just might find a new market you’ve been overlooking.
