Illustrate a powerful scene based on Revelation 7:13 - 'And one of the elders answered, saying unto me, What are these which are arrayed in white robes? and whence came they?'. The style should be inspired by the digital art medium, giving the scene a modern and vivid look. Try to capture the awe and mystery of the scene with a group of people in white robes standing under divine light, surrounded by ancient elders engaged in a contemplative dialogue.
