Visualize a spiritual scene inspired by a passage from Exodus 33:19. Show divine presence as radiant light, embodying all of goodness, passing in front of an observer. The observer stands humbly at the foot of a mountain, awe-stricken. Iridescent letters, proclaiming the name of the LORD, unfold in the sky before them. This scene is to be filled with the depiction of grace and mercy, shown through warm, gentle colors. Implement the style of digital art, using sharp geometrical shapes intermixed with fluid forms, harmoniously blending contemporary art techniques.
