Illustrate an image inspired by the passage from Revelation 22:4, capturing a devotional and respectful scenario of Christian faith. The image should emulate the traditional style of religious iconography, known for its symbolism and spiritual themes. Visualize a group of faithful individuals, with a divine symbol replacing the words mentioned in the description, on their foreheads, and all looking towards a radiant representation symbolising divine presence with awe and reverence. The colors should be rich and the aura peaceful. Do not include any text or words in the image.
