Just keep writing. Often, the feeling of losing faith is temporary. As you continue to develop the story, new ideas will come up that can boost your confidence.
Try to rewrite parts of it. Maybe the plot has holes or the characters lack depth. By reworking some elements, you can make the story more believable and interesting, thus restoring your faith. For example, if the story is a mystery and the clues don't add up, going back and adjusting them can make the whole narrative more coherent.
My faith story began when I was a child. I grew up in a religious family. Every Sunday, we would go to church together. The peaceful atmosphere, the hymns, and the sermons gradually planted the seeds of faith in me. As I grew older, I faced various challenges in life. It was during these tough times that my faith became my anchor. It gave me the strength to persevere and the hope that things would get better.
My faith has been a guiding light in my life. It has given me the courage to step out of my comfort zone. For example, I used to be shy about helping the less fortunate, but my faith taught me that it is a noble thing to do. So, I started volunteering at shelters. It has also made me more patient. When things don't go my way, I remember that there is a bigger plan. My faith has truly shaped who I am today and how I approach life.
You could take a break from it. Sometimes, distance can give you a fresh perspective. When you come back to it later, you might see things differently and regain your faith.
It might be due to comparison with other works. If they constantly compare their fictional story to highly successful or popular ones, they may start to feel that their own story is not good enough, leading to a loss of faith.
Writing a story of faith involves drawing from real-life examples, your own beliefs, and the power of imagination. Create a plot where faith is tested and emerges stronger. Make the readers feel the emotions and the importance of faith through vivid descriptions and relatable characters.
