Create a respectful and devotional Christian theme inspired by 'Matthew 5:16 - Let your light so shine before men'. Imagine a lighthouse beaming its light into the dark, serving as a metaphor to reflect on the mentioned biblical verse. The design should incorporate elements of good works, such as healthcare, education, support, and charity. Emphasize the heavenly aspect by depicting the light reaching towards a serene, celestial sky, perhaps with the silhouette of a dove flying within the beam. Please generate this in a soft, fluid style reminiscent of watercolor but no text or words should be included.
