Create a detailed piece of digital art visualizing the scene from 'Matthew 17:20'. A Middle Eastern man in traditional 1st century attire, presumably Jesus, is expressing to a diverse group of listeners of mixed gender and varied descents that if they possess faith as small as a mustard seed they can command a mountain to move. The listeners are amazed as they look to a mountain that's seemingly shifting under a clear sky, demonstrating their faith's power. The scene encapsulates an atmosphere of miracle and faith.
