Generate a digital art rendering of an open-air scene, where a gathering of people, diverse in gender and descent, watch attentively as a man in the center walks with a jubilant countenance, his hands raised as if in praise. Reference the biblical passage Acts 3:9 - 'And all the people saw him walking and praising God'. The vibrant colors of the scene should radiate the man's joy and the awe of the onlooking crowd.
