Luke 20:44 - 'David therefore calleth him Lord, how is he then his son?' Visualize this biblical verse as a thought-provoking abstract digital artwork. The artwork should feature a symbolic representation of David, perhaps in a stylized, non-realistic depiction. Use a range of vibrant colors, geometric shapes, and digital painting techniques to create this image. Pay special attention to effective use of lighting and shadow to add depth and dimension to the composition.
