Create a respectful and devotional watercolor depiction that adheres to the essence of Matthew 4:16. The scene should represent people sitting in darkness, experiencing a great, transformative light that liberates them from the shadow of death. Avoid any explicit religious symbolism, text or words in the image. The focus should lie purely on the mystical experience, the transition from darkness to light and the sense of hope and salvation derived from this transformation. Ensure the image conveys a spiritual and peaceful scene that resonates with Christian themes of faith and salvation.
