I am currently a young amateur and designing a fantasy novel. I have a character that is a half-demon who also accepted religion to cope with a tragic past. I want this character to quote scripture at certain situations that make it cool. For example, he could say "As I walk through the valley of the shadow of death, I shall fear no evil." As he walks along a path through dark, corrupted woods. My question is, is it okay to quote scripture in a novel? I hope to get this published one day but I don't want a Christianity reference to ruin my chances. Being unknown to the limits of referencing a religion. I want to know if there are any writers out there that know whats okay, and whats not. All advice appreciated. Thank you.
